Al 85.5 Ni 9.5 La 5 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.
