Abstract
The present invention relates to a method for healing amorphous alloys and an alloy suitable therefor. By measuring isothermal transformation curves regarding structural stabilization and crystallization initiation, followed by rapid cooling after structural stabilization heat treatment at a specific healing temperature, the invention standardizes structural changes according to process variables of the amorphous alloy and heals structural damage caused by elastic and plastic deformation of the amorphous alloy, thereby enabling the repeated recovery of deformation stability characteristics such as ductility and toughness as well as strength recovery. The invention also relates to a healing method and an alloy suitable therefor.
