Formation of Zr-based bulk metallic glasses from low purity materials by yttrium addition

摘要

A Zr-based bulk metallic glass formed using low purity materials at a low vacuum with a small amount of yttrium addition is provided. A method of improving the glass forming ability, crystallization and melting process without reducing the mechanical and elastic properties, such as hardness and Young's Modulus, of Zr-based alloys by yttrium addition, is also provided.
