超塑性成形是一种新影的加工方法。自从六十年代以来,主要用于特种锌和铝—铜合金材料的加工。这种工艺方法,为生产各种各样高强度和高抗腐蚀性不锈钢零件,提供了经济,和先进的生产技术。不锈钢超塑性成形与其他材料超塑性成形一样,在生产少量外形复杂的零件时,比一般方法经济的多。它利用某些合金在比较低的应力下,允许较大的塑性变形的特性。就金属材料而论,一般成形工艺,采用延伸率为0～50％,而超塑性合金却能承受延伸
Superplastic forming is a new shadow processing method. Since the sixties, it has been mainly used for the processing of special zinc and aluminum-copper alloy materials. This process method provides economical and advanced production technology for the production of a wide variety of high-strength and highly corrosion-resistant stainless steel parts. Stainless steel superplastic forming and other materials superplastic forming, in the production of a small number of complex shape parts, more economical than the average method. It utilizes the properties of certain alloys that allow for greater plastic deformation at lower stresses. In terms of metal materials, the general forming process, the elongation of 0 to 50%, while the superplastic alloy can withstand the extension
