采用两步熔融法首次合成了尺寸为1 mm的Al 85.5 Ni 9.5 La 5块体非晶合金（BMG）。该处理有效地去除了局部结构有序化和高温相，并允许高冷却速率。样品显示出良好的机械性能。压缩断裂强度约为1180 MPa，高于大多数Mg基BMG和Al合金。
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.
