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.

Methods and apparatus for forming high aspect ratio metallic glass objects, including metallic glass sheets and tubes, by a melt deposition process are provided. In some methods and apparatus a molten alloy is deposited inside a channel formed by two substrates moving relative to each other, and shaped and quenched by conduction to the substrates in a manner that enables the molten alloy to vitrify without undergoing substantial shear flow.

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.

An object is to provide a composite plating film excellent in the water-repellent property and oil-repellent property using a material that is less likely to accumulate in the environment, as substitute for a fluorine resin. A composite plating film is provided which includes an alloy matrix phase and a silicone dispersed in the alloy matrix phase. In the composite plating film, the silicone preferably has Hansen solubility parameters comprising a dispersion term .sub.D of 15 MPa.sup.1/2 or less, a polar term .sub.P of 3 MPa.sup.1/2 or less, and a hydrogen bonding term .sub.H of 3 MPa.sup.1/2 or less. The silicone preferably has an interaction radius of a Hansen solubility sphere of 5.0 MPa.sup.1/2 or less.

Provided is a method for increasing anti-galling of parts using a coating material comprising an amorphous alloy. The parts may be a vehicle or machine component, for example, that are subject to frictional and sliding forces. The disclosed coating reduces galling and friction between surfaces, and increases the lift of such parts.

A method and apparatus are described for creation of amorphous metals using electromagnetic supercooling of a metal/alloy without the utilization of rapid quenching or immaculate process environments. By exposing the cooling melt to electric currents, either induced by an alternating current (AC) magnetic field or supplied directly, crystallization is suppressed, and the melt can reach significant levels of supercooling. With sufficient current densities in the melt, the supercooling can extend all the way into the glass transition range for certain materials, at which point an amorphous metal/alloy is created.
