The invention relates to a method for thermally stable joining of a glass element to a support element, wherein the glass element has a first coefficient of expansion and the support element has a second coefficient of expansion differing from the first coefficient of expansion. The method thus comprises a step of attaching an intermediate glass material to the support element, wherein the intermediate glass material has a third coefficient of expansion which substantially corresponds to the second coefficient of expansion. In addition, the method comprises a step of local heating of the intermediate glass material in order to join the glass element to the support element via the intermediate glass material.

Joining methods and corresponding structures are disclosed. In some instances, a method for joining two or more components may include generating a shockwave in a first component to form a jet of a material of the first component directed towards a second component. The jet may penetrate the second component to connect the first component with the second component. Articles of pre-joined and joined components are also described.

An embodiment relates to an ultrasonic additive manufacturing process, comprising joining a foil comprising a bulk metallic glass to a substrate; and forming a cladded composite comprising the foil and the substrate; wherein a thickness of the cladded composite is greater than a critical casting thickness of the bulk metallic glass, wherein the cladded composite comprises a cladding layer of the bulk metallic glass on the substrate and the bulk metallic glass comprises approximately 0% crystallinity, approximately 0% porosity, less than 50 MPa thermal stress, approximately 0% distortion, approximately 0 inch heat affected zone, approximately 0% dilution, and a strength of about 2,000-3,500 MPa.

A tube assembly includes at least first and second tubes configured for coupling at respective ends. The first and second tubes each include a base material, and a weld interface at the respective end. The weld interface is proximate to an inner diameter and an outer diameter of the first and second tubes, and includes a weld interface segment extending therebetween. A work hardened weld assembly couples the base material of each of the first and second tubes. The work hardened weld assembly includes a weld fusion zone between the weld interfaces of the first and second tubes and the weld interface segments of the first and second tubes. The weld fusion zone is work hardened and at least the weld interface segments of the first and second tubes are work hardened between the work hardened weld fusion zone and the base material of the first and second tubes.

A fastening inclusion is provided and includes a hard point made of coalesced metal sheets, metal or fiber flanges extending from edges of the hard point, and a fastener arranged on the hard point. The fastening inclusion can be incorporated into a fiber reinforced polymer structure by interleaving the flanges with fiber reinforced resin plies, and then curing the fiber reinforced plies to form a composite structure. The fastener on the hard point may be used for mechanically connecting the composite structure to a separate component, such as a metal component on a vehicle.

A pressure measuring device includes a ceramic pressure sensor including a ceramic measuring membrane and a sensor mounting configured to secure the pressure sensor such that a membrane region of the measuring membrane surrounded by a membrane edge is contactable with a medium having a pressure to be measured. The sensor mounting includes a titanium or titanium alloy mounting element including an opening through which the membrane region is contactable with the medium. The membrane edge is connected directly with the mounting element by a diffusion weld produced by a diffusion welding method.

A first member and a second member are formed of metal materials of the same type and a third member is formed of a material of a different type that is difficult to weld to the first member and the second member. The first member and the second member are welded to each other via a through hole with the third member interposed therebetween in a region corresponding to a first protrusion. For the first member and the third member, and the second member and the third member, each of respective outer peripheral portions of an overlapping portion of the first member and the third member and an overlapping portion of and the second member and the third member is welded.

Methods of fastening are provided. A method comprises contacting a fastener with a first layer of an assembly at a first location. The assembly comprises the first layer, a third layer, and a second layer positioned intermediate the first layer and the third layer. The first layer, the third layer, and the fastener are electrically conductive. The second layer defines a gap and the first location is in communication with the gap. Electrical communication is formed between the assembly and the fastener. The first layer is fastened to the third layer through the gap in the second layer with the fastener. The fastening comprises resistance welding the fastener to the third layer.
