SHAPING OF AMORPHOUS METAL ALLOYS
Disclosed is a method of brazing articles together to form at least one braze defined by complementarily curved faying surfaces on the articles, the faying surfaces each having at least one region of curvature comprising at least one point from which the surface curves in more than one direction, the method comprising the steps of: a) disposing between the complementarily curved faying surfaces at least one amorphous brazing alloy preform of complementary curvature at least in part to said at least one region of the complementarily curved faying surfaces to conform to the complementarily curved faying surfaces in said region; and b) heating the articles and at least one amorphous brazing alloy preform to a brazing temperature at which the amorphous brazing alloy flows and brazes. and brazing alloy preforms for use in such methods. Methods of forming an article comprising a curved surface from a sheet of an amorphous metal alloy are disclosed, by applying heat from a fluid to a sheet of the amorphous metal alloy to raise at least a portion of the sheet to a temperature above the glass transition temperature T.sub.g and below the crystallization temperature T.sub.x.

High Entropy Alloy Having Composite Microstructure and Method of Manufacturing the Same
A metallic alloy, more particularly, a high-entropy alloy with a composite structure exhibits high strength and good ductility, and is used as a component material in electromagnetic, chemical, shipbuilding, machinery, and other applications, and in extreme environments, and the like.
Amorphous metal rivet systems
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.
