    摘要： A family of rivets including both blind and bucked-type rivets made at least partially from an amorphous metal alloy. A blind rivet includes a head portion and a tail portion. At least one of the head portion and the tail portion is configured to elastically deform to secure a first member in position relative to a second member. The head portion and the tail portion may include one or more deformable legs having an interface feature configured to engage with one of the first member and the second member. A bucked-type rivet assembly includes a formable member and an anvil. The anvil is configured to thermoplastically deform the formable member proximate to the second member by passing current through an electrical circuit that includes at least one of the formable member and anvil.

    摘要： High-strength, lightweight alloy components, such as automotive components, capable of high temperature performance comprising aluminum, silicon, and iron and/or nickel are provided, along with methods of making such high-strength, lightweight alloy components. A high-energy stream, such as a laser or electron beam, may be selectively directed towards a precursor material to melt a portion of the precursor material in a localized region. The molten precursor material is cooled at a rate of greater than or equal to about 1.0×105 K/second to form a solid high-strength, lightweight alloy component comprising a stable ternary cubic phase having high heat resistance and high strength. The stable ternary phase may be AlxFeySiz, where x ranges from about 4 to about 5 or about 7.2 to about 7.6, y is about 1.5 to about 2.2, and z is about 1. The stable ternary phase may also be Al6Ni3Si.

    摘要： The disclosure is directed to freefall methods and apparatuses for preparation of amorphous BMG feedstock and sheet material. In certain aspects, the disclosure relates to methods and apparatuses for contactless formation of BMG feedstock and sheet material via a drop-tower. In certain embodiments, the methods comprise releasing droplets of molten amorphous alloy into a cooled, pressurized chamber of a drop-tower, wherein the droplets traverse the chamber through freefall to thereby form BMG feedstock or sheet material.

    摘要： An aluminum base alloy is produced by supercooling a molten alloy composed mainly of aluminum. The molten alloy contains an element capable of forming a quasicrystalline phase, an element which aids formation of the quasicrystals, and an element which stabilizes a supercooled state of the molten alloy and delays crystallization of a crystalline phase, and is composed of a mixed composition of a fine amorphous phase and an aluminum crystalline phase or an aluminum supersaturated solid solution phase, or a single phase of only an amorphous phase.
