前言近年来关于超塑性的国际会议,越来越频繁了。去年(1935),在英国召开了“航空铝合金超塑性”会议,继而又在法国召开了“超塑性”会议,人们可以认为超塑性材料的研究业已进入了一个新的阶段。这些会议使航空航天工业界及飞机制造厂家,很快地认识到超塑性加工方法是实用性很广的加工方法,它可以 Preface In recent years, international conferences on superplasticity have become more frequent. Last year (1935), held in the United Kingdom “aviation superplastic alloy” meeting, followed by held in France, “superplastic” meeting, one can think of superplastic materials research has entered a new phase. These conferences have enabled the aerospace industry and aircraft manufacturers to quickly recognize that superplastic processing methods are a practical method of processing that can
