Bulk metallic glass rings prepared by a modified water quenching method

Bulk metallic glass rings have the potential applications as annular gasket and active solder in special fields.The bulk me-tallic glass ring of Zr41.2Ti13.8Cu12.5Ni10.0Be22.5 with the outer diameter,the inner diameter,and the thickness of 38,36,and 5 mm,re-spectively,was prepared by using a special shaped quartz tube water quenching method.The mechanical properties along the whole cross section were investigated by a nanoindentation method,and no evident variation of the Young's modulus and hardness was found,further indicating the single amorphous structure.Amorphous ring and tube-shape parts with different dimensions can be produced by this method.
