对ZA22合金超塑态组织、空冷组织、淬火组织进行拉伸试验研究。结果表明，在适宜的组织、温度、形变这事条件下，ZA22合金具有半固态超塑性、此时应变速率敏感系数。值为0。49。晶界微馆为超塑性的产生创造了有利的条件 ZA22 alloy superplastic microstructure, air-cooled tissue, quenched tissue tensile test. The results show that the ZA22 alloy has a semi-solid superplasticity under the proper conditions of microstructure, temperature and strain, and the strain rate sensitivity coefficient at this time. The value is 0.49. Grain boundary micro-museum for the production of super-plastic created favorable conditions
