在ECAP处理的材料中观察到了优异的低温超塑性（<300 °C）：ZK60和AZ91合金在3×10−3s− 1应变速率下的断裂伸长率分别为810%和570%。内耗可用于确定超塑性的最佳温度。
Excellent low-temperature superplasticity (<300 °C) was observed in the ECAP-processed materials: elongations to failure are 810% and 570% at a strain rate of 3×10−3s−1for ZK60 and AZ91 alloys, respectively. Internal friction can be practically used to determine the optimum temperature for superplasticity.
