摘要: Bulk metallic glasses are prepared in Pd40.5Ni40.5SixP19−x (x = 0–14 at.%) alloys by a combination of flux treatment and water quenching technique. It is found that the thermal stability glassy depends on addition Si content. Among studied, Pd40.5Ni40.5Si5P15 bulk glass exhibits largest supercooled liquid region (ΔT 119 K) highest activation energy crystallization (283.3 kJ/mol), showing enhanced formation ability extraordinary stability.
