Abstract:
A manufacturing method for zirconium system amorphous alloy, comprising the steps of:melting metal by a high energy heat source; pressing the molten metal in a press such that the molten metal does not form fitting cooling faces having a temperature under melting point of the molten metal; transforming the molten metal at a temperature over the melting point into a predetermined configuration by applying at least one stress selected from compressive stress and shearing stress; and cooling the molten metal at over a critical cooling rate simultaneously with or after the transformation to make the zirconium system amorphous alloy in the predetermined configuration which has a composition expressed by a general formula: Zr100-x-y-a-b Tix Aly Cua Nib (marks a, b, x, and y in the formula represent atomic percentage, and they fulfill X<10, Y>5, Y6 cm.
