Abstract: A method of producing a compact of amorphous alloy, comprising the steps of, preparing a billet by filling a container made of a ductile metal with powder of the amorphous alloy, plastically working said billet at a temperature higher than plasticity transition temperature of the amorphous alloy but less than crystallization temperature of said alloy so that both a shear strain of not less than about 0.7 but less than 1.8 and a stress not less than about 90 Kgf/mm.sup.2 and less than 400 Kgf/mm.sup.2 are applied to the amorphous alloy powder filled in the container.
