Abstract

Bulk metallic glasses are prepared in Pd_40.5Ni _40.5Si_xP_19-x (x ≤ 0-14 at.%) alloys by a combination of flux treatment and water quenching technique. It is found that the thermal stability of the Pd_40.5Ni_40.5Si _xP_19-x glassy alloys depends on the addition of Si content. Among the Pd_40.5Ni_40.5Si_xP _19-x glassy alloys studied, the Pd_40.5Ni _40.5Si₅P₁₅ bulk metallic glass exhibits the largest supercooled liquid region (ΔT ≤ 119K) and the highest activation energy of crystallization (283.3kJ/mol), showing enhanced glass formation ability and extraordinary glassy thermal stability.
