摘　　要：对大块非晶合金在过冷液相区内的超塑性变形特点进行了评述。介绍了在过冷液相区内的流变行为和变形后的组织结构变化,并解释了超塑性变形的机理。同时,对大块非晶合金的超塑性成形技术发展现状况进行了概述。Superplastic behaviors of bulk amorphous alloys in the supercooled liquid region were reviewed. The flow behaviors in the supercooled liquid region and its changes of structure after deforming process were introduced and the superplastic deformation mechanism of bulk amorphous alloys was explained briefly as well. At the same time, the current status and development in techniques of forming bulk amorphous alloys were generally summarized.

关 键 词：大块非晶合金 过冷液相区 超塑性
