Synthesis and Properties of Al‐Ni‐La Bulk Metallic Glass

Abstract

Al85.5Ni9.5La5 bulk metallic glass (BMG) with a size of 1 mm is synthesized for the first time through a two-step melt treatment. The treatment effectively removes the local structural ordering and high-temperature phases, as well as allowing a high cooling rate. The sample displays good mechanical properties. The compressive fracture strength is about 1180 MPa, which is higher than that of most Mg-based BMGs and Al alloys.
