材料高温超塑性拉伸试验方法至今尚未统一,这对材料研制及其加工工艺制订均为不利。本文设计出一种可供统一使用的试验方法,以克服这一不足,并取得了很好的实用效果。

An experimental method of the high temperature superplasticity which has not standardized up to now is very unfavourable to develop new-type materials and to formulate a processing technology, There is presented that the method has been designed to overcome this insufficient and a good results is yielded in practice.
