Catching the Ni-based ternary metallic glasses with critical diameter up to 3 mm in Ni–Nb–Zr system

The Ni-based ternary bulk metallic glasses (BMGs) with critical diameter up to 3 mm were discovered in Ni–Nb–Zr system using a strategy for catching the best glass former based on relative glass forming ability of alloys. The best glass former Ni62Nb33Zr5 exhibits glass transition temperature of 877 K, supercooled liquid region of 40 K, compressive strength of about 3 GPa, plastic strain of about 1%.
