标准摘要
[中文适用范围]： 本国际标准规定了一种评估金属超塑性材料的拉伸性能的方法，该材料表现出所谓的“细晶粒超塑性”，没有明显的加工硬化或动态微观结构演变，通过对平板试件以恒定横梁速度进行拉伸试验，不连接引伸计。 [外文原描述]： ISO 20032:2013 specifies a method for evaluating the tensile properties of metallic superplastic materials which exhibit what is called "Fine-Grained Superplasticity", without significant work-hardening or dynamic microstructure evolution, by means of a tensile test at constant cross-head velocity, for flat-form test pieces, without an extensometer attached.
