The BMG structure may be configured to be under a direct exposure to hydrogen, wherein hydrogen is on the internal surface of the structure and is not on the exterior of the structure during operation.

The present invention provides a heat treatment method and a heat treatment apparatus for an amorphous alloy ribbon, said method and apparatus being capable of uniformly heat treating an amorphous alloy ribbon, while suppressing the occurrence of anisotropy in the magnetic characteristics. A heat treatment method for an amorphous alloy ribbon, said method comprising a step wherein an amorphous alloy ribbon is transferred, while being in contact with a heated projected surface, and the amorphous alloy ribbon is transferred, while having the part that is in contact with the projected surface pressed against the projected surface from a surface which is on the reverse side of the surface that is in contact with the projected surface.

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.
