DETAILED DESCRIPTION

(9) Turning now to the drawings, systems and methods for structurally interrelating two components using inserts made from metallic glass-based materials are illustrated. In many embodiments, threaded inserts that include metallic glass-based materials are embedded within at least a first component to be adjoined to a second component; the threaded insert is then utilized in the adjoining of the at least two components. In a number of instances, cup and cone-shaped inserts that include metallic glass-based materials are embedded within first and second components, and the cup and cone-shaped inserts are used to structurally align the first and second components.

(10) Metallic glasses, also known as amorphous alloys, embody a relatively new class of materials that is receiving much interest from the engineering and design communities. Metallic glasses are characterized by their disordered atomic-scale structure in spite of their metallic constituent elementsi.e. whereas conventional metallic materials typically possess a highly ordered atomic structure, metallic glass materials are characterized by their disordered atomic structure. Notably, metallic glasses typically possess a number of useful material properties that can allow them to be implemented as highly effective engineering materials. For example, metallic glasses are generally much harder than conventional metals, and are generally tougher than ceramic materials. They are also relatively corrosion resistant, and, unlike conventional glass, they can have good electrical conductivity. Importantly, metallic glass materials lend themselves to relatively easy processing in certain respects. For example, the forming of metallic glass materials can be compatible with injection molding processes. Thus, for example, metallic glass compositions can be cast into desired shapes.

(11) Nonetheless, the practical implementation of metallic glasses presents certain challenges that limit their viability as engineering materials. In particular, metallic glasses are typically formed by raising a metallic alloy above its melting temperature, and rapidly cooling the melt to solidify it in a way such that its crystallization is avoided, thereby forming the metallic glass. The first metallic glasses required extraordinary cooling rates, e.g. on the order of 10.sup.6 K/s, and were thereby limited in the thickness with which they could be formed. Indeed, because of this limitation in thickness, metallic glasses were initially limited to applications that involved coatings. Since then, however, particular alloy compositions that are more resistant to crystallization have been developed, which can thereby form metallic glasses at much lower cooling rates, and can therefore be made to be much thicker (e.g. greater than 1 mm). These metallic glass compositions that can be made to be thicker are known as bulk metallic glasses (BMGs). As can be appreciated, such BMGs can be better suited for investment molding operations.

(12) In addition to the development of BMGs, bulk metallic glass matrix composites (BMGMCs) have also been developed. BMGMCs are characterized in that they possess the amorphous structure of BMGs, but they also include crystalline phases of material within the matrix of amorphous structure. For example, the crystalline phases can exist in the form of dendrites. The crystalline phase inclusions can impart a host of favorable materials properties on the bulk material. For example, the crystalline phases can allow the material to have enhanced ductility, compared to where the material is entirely constituted of the amorphous structure. BMGs and BMGMCs can be referred to collectively as BMG-based materials. Similarly, metallic glasses, metallic glasses that include crystalline phase inclusions, BMGs, and BMGMCs can be referred to collectively as metallic glass-based materials or MG-based materials.

No. 14/971,848, is hereby incorporated by reference in its entirety, especially as it pertains to the manufacture of metallic glass-based gearbox housings.

(14) Notwithstanding all of these developments, the vast potential of metallic glass-based materials has yet to be fully appreciated. For instance, the fabrication of inserts that can be used to facilitate the structural interrelationship between two components from metallic glass-based materials has yet to be fully explored. Such inserts have typically been fabricated from conventional engineering materials such as steel, aluminum, and/or titanium. This is in part due to the conventional desire to not have two dissimilar metals in intimate contact with each otheri.e. a screw and the respective threaded insert each including dissimilar metalsfor fear of the effects of galvanic corrosion. However, MG-based materials can be made to be relatively averse to the effects of galvanic corrosion, and can also be made to develop a robust oxide layer that can further inhibit occurrences of galvanic corrosion. In other words, MG-based materials can be made to practicably operate in intimate contact with dissimilar metals. Whereas such inserts have typically been fabricated from conventional engineering materials (e.g. steel, aluminum, or titanium), they can substantially benefit from the materials properties that many MG-based materials can offer. For instance, inserts made from MG-based materials can have a relatively higher elastic strain limit, better resistance to wear, higher hardness, lower density, better corrosion resistance, and/or better resilience to extreme environments relative to conventionally fabricated inserts. Additionally, MG-based materials can be further advantageous insofar as their inherent mechanical properties can be tunable via alloying. Moreover, MG-based materials are amenable to casting and other thermoplastic forming processes, which can greatly enhance manufacturing efficiency. By contrast, casting processes are not conventionally used in the fabrication of inserts from heritage engineering materials for a number of reasons. For example, the most appropriate conventional materials for casting techniques are softer materials, which typically are not wear resistant and thereby not best-suited for, e.g., threaded insert applications where screws may be wearing on the respective insert. Methods for structurally interrelating two components using inserts that include MG-based materials in accordance with many embodiments of the invention are now discussed below.

(15) Methods for Structurally Interrelating Two Components Using Inserts Fabricated From MG-Based Materials

(16) In many embodiments of the invention, two components are structurally interrelated using inserts fabricated from MG-based materials. While conventional inserts fabricated from heritage engineering materials have been effective in many respects, fabricating these inserts from MG-based materials can offer a host of previously unrealized advantages. As alluded to above, MG-based materials can offer unique materials profiles that can be advantageous such inserts. Moreover, MG-based materials are amenable to casting and other thermoplastic forming processes, which can allow for the efficientandbulk manufacture of even intricate geometries. For example, FIG. 1 illustrates a screwincluding threadsthat was entirely cast from a MG-based material; FIG. 1 demonstrates that MG-based materials can be cast into intricate geometric shapes. This level of castability can be harnessed in the creating inserts from metallic glass-based materials.

(17) FIG. 2 illustrates a process for structurally interrelating two components in accordance with certain embodiments of the invention. In particular, the method 200 includes forming 210 an insert from a MG-based composition using a casting technique or other thermoplastic forming technique. Any suitable thermoplastic or casting technique can be implemented in accordance with embodiments of the invention. For example, FIGS. 3A-3C schematically illustrate casting a MG-based material to create a threaded insert in accordance with many embodiments of the invention. In particular, FIG. 3A illustrates a MG-based composition in relation to a mold in the shape of a screw; FIG. 3B illustrates casting the MG-based melt around the mold so as to form a MG-based material; and FIG. 3C illustrates removing the cast threaded insert from the plug. In many instances, the forming 210 additionally includes other manufacturing procedures, such as machining. For instance, the forming 210 can include roughening the outer surface of the insert via any of a variety of texturizing techniques.

(18) Note that any suitable MG-based material can be incorporated in accordance with embodiments of the invention; embodiments of the invention are not limited to particular compositions. For example, in many instances, the alloy composition is a composition that is based on one of: Ti, Zr, Cu, Ni, Fe, Pd, Pt, Ag, Au, Al, Hf, W, TiZrBe, CuZr, ZrBe, TiCu, ZrCuNiAl, TiZrCuBe and combinations thereof. In the instant context, the term based on can be understood to mean that the specified element(s) are present in the greatest amount relative to any other present elements. Additionally, within the context of the instant application, the term MG-based composition can be understood reference an element, or aggregation of elements, that are capable of forming a metallic glass-based material (e.g. via being exposed to a sufficiently rapid, but viable, cooling rate). While several examples of suitable metallic glass-based materials are listed above, it should be reiterated that any suitable metallic glass-based composition can be incorporated in accordance with embodiments of the invention; for example, any of the metallic glass-based compositions listed in the disclosures cited and incorporated by reference above can be implemented. In many instances, the particular MG-based composition to be cast is based on an assessment of the anticipated operating environment for the insert. Thus, for example, in many instances the implemented MG-based composition is based the desire to match the coefficient of expansion with that of the component material that it is going to be affixed to. Accordingly, in many embodiments, titanium-based MG-based materials are implemented for use in conjunction with carbon composite materials. In particular, both titanium-based MG-based materials and carbon composite materials are generally characterized by relatively low coefficients of thermal expansion. In this way, when the insert is affixed to the carbon composite, the stresses between the insert and the carbon composite (e.g. in the epoxy bonding) can be reduced. Note also that both titanium-based MG-based materials and carbon composites are relatively light weight materials, and can thereby be well-suited for space applications. In particular, titanium-based MG-based inserts can offer high hardness at a relatively low density.

(19) In many instances, the selection of the MG-based material to be implemented is based on the desire for one of: environmental resilience, toughness, wear resistance, hardness, density, machinability, and combinations thereof. For reference, Tables 1-6 list materials data that can be relied on in selecting a metallic glass-based composition to be implemented.

(26) Again, while several examples of MG-based materials that can be suitable for implementation within the instant context, embodiments of the invention are not limited to the materials listed in the tables. Rather, any suitable MG-based material can be implemented in accordance with embodiments of the invention.

(27) Importantly, the MG-based composition can be cast into any suitable shape that can facilitate the structural interrelationship between two components. For example, FIGS. 4A-4I depict various geometries that can also be implemented in accordance with embodiments of the invention. Note that FIGS. 4A-4E illustrate threaded insert geometries that are characterized by a rough-textured outer surface, which can facilitate the bonding of the insert to a component. Of course, it should be appreciated that while certain rough textured surfaces are depicted, any of a variety of rough-textured surfaces can be incorporated in accordance with embodiments of the invention. FIG. 4F illustrates an eye-hook geometry can be used to facilitate a tethering structural relationship. In many instances, the formed insert is a threaded insert that includes extensions that flare out when engaged by a screw; extensions can serve to better grip an associated component. FIGS. 5A-5C illustrate a threaded insert that includes extensions that deploy when the insert engages a screw in accordance with an embodiment of the invention. In particular, FIG. 5A illustrates a screw and an insert made from a MG-based material in accordance with an embodiment of the invention. FIG. 5B illustrates the screw being inserted into the threaded insert, and the extensions beginning to deploy. FIG. 5C illustrates that the screw is fully engaged with the threaded insert, and the extensions are fully deployed. This type of design can help the insert better adhere to a component that it is affixed to. To be clear, while several designs have been discussed and illustrated, any suitable insert design can be implemented in accordance with embodiments of the invention. For example, in some embodiments, cup and cone-shaped inserts are fabricated. Cup and cone-shaped inserts can be affixed to first and second components respectively, and can be used to align the first and second component materials. To reiterate, any suitable insert shape can be implemented in accordance with embodiments of the invention.

(28) Returning back to FIG. 2, the method 200 further includes affixing 220 the insert to a first component that is to be structurally interrelated to a second component. The insert can be affixed 220 in any suitable way in accordance with embodiments of the invention. For example, in many embodiments, the insert is epoxy bonded to the component. In a number of embodiments, the operation of a mechanical lock (e.g. the extensions depicted in FIGS. 5A-5C) is relied in affixing the insert to the component. Any suitable technique can be used to affix the insert to the component. In some embodiments, the elastic nature of the constituent MG-based material is relied on to allow the insert to better adhere to a respective component. For example, in some embodiments, a threaded insert is affixed to a component via a press fit; subsequently, when a screw engages the threaded insert, it expands laterally, and thereby better adheres to the component. Note that MG-based materials can have elastic limits as high as 2% or more; accordingly they can accommodate a relatively substantial amount of elastic deformation, which in turn can be used to better affix the insert to the component. FIGS. 6A-6B illustrate a threaded insert fabricated from a MG-based material that expands upon engagement with a screw and thereby better adheres to its respective associated component in accordance with an embodiment of the invention. In particular, FIG. 6A depicts the insert press-bonded to an associated component; the depicted gap is meant to indicate that the insert is not as tightly bonded to the component as it could be. FIG. 6B illustrates that as the screw begins to engage the insert, it expands laterally and thereby more strongly adheres to the associated component. While several examples of affixing an insert to a component are discussed, it should be clear that any suitable way of affixing the insert to a first component can be implemented in accordance with embodiments of the invention.

(29) Note that the component that the insert is affixed to can be any suitable component in accordance with embodiments of the invention. In many embodiments, the component is in the form of a sheet (e.g. sheet metal). In numerous embodiments, the component made from a relatively modern material, such as a carbon composite material. To be clear though, the component can take any of a variety of forms in accordance with embodiments of the invention.

(30) Returning back to FIG. 2, the method 200 further includes structurally interrelating 230 a second component to the first component using the insert. In many embodiments, the insert is a threaded insert, a screw is used to fasten the second component to the first component using the threaded insert, and the first and second components are thereby structurally interrelated. In a number of embodiments, the insert is a cup-shaped insert designed to accommodate a cone-shaped geometry, the second component has an included cone-shaped geometry, the cup-shaped insert is used to align the first and second components, and the first and second components are thereby structurally interrelated. While several examples are given, it should be clear that the first and second components can be structurally interrelated in any suitable way in accordance with embodiments of the invention.

(31) FIGS. 7A-7D schematically illustrates one example of a process in accordance with the method outlined in FIG. 2. In particular, FIG. 7A illustrates a first component to be structurally interrelated to a second component; in the illustrated embodiment, the first component is in the form of a sheet. As alluded to above, the component can be any suitable material in accordance with embodiments of the invention. FIG. 7B illustrates the formation of a threaded insert from a MG-based material. The insert can be formed using any suitable technique in accordance with embodiments of the invention, including any of the above-listed techniques. FIG. 7C illustrates embedding the insert within the first component. In particular, it is depicted that the insert is embedded within the first component using epoxy bonding. Of course, while epoxy bonding is depicted, the insert could have been affixed to the first component using any suitable technique in accordance with embodiments of the invention. FIG. 7D illustrates fastening a second component to the first component using a screw. As can be appreciated from the above discussion, the second component can take any of a variety of forms in accordance with embodiments of the invention. For example, it can conform to any of a variety of suitable geometries, and it can be made from any of a variety of suitable materials. While a certain process has been schematically illustrated in FIGS. 7A-7D, it should be clear that the process described with respect to FIG. 3 can be implemented in any of a variety of ways in accordance with embodiments of the invention.

(32) FIGS. 8A-8B illustrate views of a MG-based insert relative to a conventional, steel-based insert. In particular, the MG-based insert appears on the right side of FIGS. 8A and 8B. Note that the two inserts are virtually identical in geometry, which demonstrates the viability of fabricating inserts from MG-based materials.

(33) In general, as can be inferred from the above discussion, the above-mentioned concepts can be implemented in a variety of arrangements in accordance with embodiments of the invention. For example, while the process listed in FIG. 3 recites forming an insert using either a thermoplastic forming technique or a casting technique, in many embodiments, the insert is formed without using one of those techniques. Any suitable manufacturing technique can be used to form an insert from a metallic glass-based material in accordance with embodiments of the invention. Accordingly, although the present invention has been described in certain specific aspects, many additional modifications and variations would be apparent to those skilled in the art. It is therefore to be understood that the present invention may be practiced otherwise than specifically described. Thus, embodiments of the present invention should be considered in all respects as illustrative and not restrictive.
