Abstract：

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.
