ABSTRACT:
Disclosed herein is a process for forming an amorphous alloy material capable of showing glass transition, which comprises holding the material between frames arranged in combination; and heating the material at a temperature between its glass transition temperature (Tg) and its crystallization temperature (Tx) and, at the same time, producing a pressure difference between opposite sides of the material, whereby the material is brought into close contact against a forming mold disposed on one side of the material. As an alternative, the forming mold is brought into close contact against the amorphous material in a direction opposite to the pressing direction for the amorphous material. By the above processes, precision-formed products of amorphous alloys can be manufactured and supplied at low cost. These formed amorphous alloy products can be used as mechanical structure parts and components of high strength and high corrosion resistance, various strength members, electronic parts, arts and crafts, original printing plates, or the like.
