摘要

采用SIMA工艺制备了7075铝合金半固态触变坯料

对不同温度、不同保温时间下的7075铝合金触变坯料的微观组织进行了观察分析。结果表明

在温度为600℃、保温时间为45 min时及在温度为615℃、保温时间为15 min时都可以获得良好的半固态组织。

Abstract

7075 aluminum alloy semi-solid billets were prepared by SIMA technology. Effects of holding temperature and holding time on microstructure of 7075 aluminum alloy thixotropic billets were analyzed. The results reveal that the desirable semi-solid structure in the thixotropic billets can be observed at 600 ℃ for 45 min or at615 ℃ for 15 min.
