ABSTRACT:
A process for producing a structural member of an amorphous alloy, which includes the steps of subjecting a material formed from an amorphous alloy having a glass transition temperature Tg and a crystallization temperature Tx, which is higher than the glass transition temperature Tg, to a thermal treatment in which the material is kept at a heating temperature equal to or lower than the glass transition temperature Tg, thereby generating a structure relaxation phenomenon in the material, and subjecting the material to a hot plastic working while setting the hot working start temperature of the green compact at a level equal to or lower than the crystallization temperature Tx. In this process, the workability of the material can be improved to produce a high strength amorphous alloy structural member that has an increased volume fraction of an amorphous phase. Furthermore the generation of any defect due to gas inclusion is suppressed.
