日本名古屋工业技术研究所的马渊守等人阐述了超塑性的一般特征、高速超塑性的最新研究进展及在航空航天器构件上的应用实例。超塑性对于多晶材料来说，应变依存于高应变速率，不产生缩颈而能延伸百分之几百。具有大延伸率、大应变速率敏感性指数和小流变应力的超塑性材料能够 Japan’s Nagoya Institute of Technology, Ma Yuan Shou and others described the general characteristics of superplastic, superplasticity of the latest research and application in aerospace components. Superplasticity For polycrystalline materials, the strain depends on the high strain rate and can extend hundreds of percent without producing constrictions. Superplastic materials with large elongation, large strain rate sensitivity index and low flow stress can
