ABSTRACT:
Amorphous alloys containing zirconium as an amorphous forming metal and having teh formula X.sub..alpha. Z.sub..gamma. wherein X is at least one of Fe, Co and Ni, .alpha. is 80 to 92 atomic %, Z is zirconium, .gamma. is 8 to 20 atomic % and the sum of .alpha. and .gamma. is 100 atomic %, cause little variation of properties during aging and embrittlement because they contain no metalloid as the amorphous forming element, and they further have excellent strength, hardness, corrosion resistance and heat resistance and maintain superior magnetic properties which are characteristic of iron group elements.
