Amorphous alloys containing iron group elements and zirconium and articles made of said alloys

摘要

Amorphous alloys containing zirconium as an amorphous forming metal and having teh formula X alpha Z 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.
