ABSTRACT:
This invention deals with a method of producing a bulk amorphous metal alloy article. The method involves mechanically alloying an amorphous matrix material and a crystalline element which is a fast diffuser in the matrix material to give a powder mixture which is at least 50% but less than 100% amorphous. This powder mixture is then formed into a bulk amorphous metal alloy article by ordinary forming methods such as hot-pressing. The resultant bulk amorphous metal alloy article can be heated above its glass transition temperature to provide a bulk crystalline metal alloy article.
