Embodiments disclosed herein relate to production of amorphous alloys having compositions of iron, chromium, molybdenum, carbon and boron for usage in additive manufacturing, such as in layer-by-layer deposition to produce multi-functional parts. Such parts demonstrate ultra-high strength without sacrificing toughness and also maintain the amorphous structure of the materials during and after manufacturing processes. An Amorphous alloy composition has a formula Fe.sub.100-(a+b+c+d)Cr.sub.aMo.sub.bC.sub.cB.sub.d, wherein a, b, c and d represent an atomic percentage, wherein: a is in the range of 10 at. % to 35 at. %; b is in the range of 10 at. % to 20 at. %; c is in the range of 2 at. % to 5 at. %; and d is in the range of 0.5% at. % to 3.5 at. %.

Exemplary embodiments described herein relate to methods and apparatus for forming a coating layer at least partially on surface of a BMG article formed of bulk solidifying amorphous alloys. In embodiments, the coating layer may be formed in situ during formation of a BMG article and/or post formation of a BMG article. The coating layer may provide the BMG article with surface hardness, wear resistance, surface activity, corrosion resistance, etc.

The present invention includes composition and methods for the fabrication of very-high-aspect-ratio structures from metallic glasses. The present invention provides a method for nondestructive demolding of templates after thermoplastic molding of metallic glass features.

The embodiments described herein relate to BMG articles with high bulk having all dimensions greater than the critical dimension. Exemplary BMG article can include at least one bulk component and/or one or more fixation elements configured on surface of the bulk component or inserted into the bulk component. Other embodiments relate to methods of making the BMG articles by thermo-plastic-formation of BMG alloy materials.

Various embodiments provide apparatus and methods for melting materials and for containing the molten materials within melt zone during melting. Exemplary apparatus may include a vessel configured to receive a material for melting therein; a load induction coil positioned adjacent to the vessel to melt the material therein; and a containment induction coil positioned in line with the load induction coil. The material in the vessel can be heated by operating the load induction coil at a first RF frequency to form a molten material. The containment induction coil can be operated at a second RF frequency to contain the molten material within the load induction coil. Once the desired temperature is achieved and maintained for the molten material, operation of the containment induction coil can be stopped and the molten material can be ejected from the vessel into a mold through an ejection path.

An embodiment relates to a material comprising a ceramic formed from an amorphous metal alloy (amorphous metal ceramic composite), wherein the composite exhibits a higher corrosion resistance than that of Haynes 230 when exposed to molten chlorides such as KCl or MgCl.sub.2 or combinations thereof at temperatures up to 750° C. Yet, another embodiment relates to a method comprising obtaining a substrate, forming a coating of an amorphous metal alloy, heating the coating, and transforming at least a portion the amorphous metal alloy into an amorphous metalceramic composite.

A sulfurous, metallic glass forming alloy and a method for the production thereof are described.

Extreme ultraviolet (EUV) mask blanks, methods for their manufacture and production systems therefor are disclosed. The EUV mask blanks comprise a substrate; a multilayer stack of reflective layers on the substrate; a capping layer on the multilayer stack of reflecting layers; and an absorber layer on the capping layer, the absorber layer comprising an alloy selected from an alloy of ruthenium (Ru) and silicon (Si); an alloy tantalum (Ta) and platinum (Pt); and an alloy of ruthenium (Ru) and molybdenum (Mo).

A pressure vessel containing a main body with at least one opening. The pressure vessel is made from a BMG material. The pressure vessel may contain an additional part such as a neck, a liner, a rib, a lattice, a fin, and a diaphragm. The pressure vessel may be free of a welded joint in entirety. The pressure vessel may contain multiple parts in the main body, each of which is free of a welded joint. The pressure vessel may be made through thermoplastic forming.
