Paper Title:
Deformation Behavior of Aluminum Alloy during Semi-Solid Compression
  Abstract

By semi-solid aluminum alloy compression test, deformation mechanism of semi-solid aluminum alloy was investigated, the thixotropic strength existing in semi-solid aluminum alloy was verified and the influences of temperature and strain rate on the deformation mechanism and thixotropic strength were discussed. The results show that there are 4 stages in the process of compression deformation for semi-solid aluminum alloy: stress swift growth stage, stress drop stage, steady stress stage and stress gradual growth stage. The semi-solid billet has a thixotropic strength, which is sensitive to temperature and strain rate. The higher the temperature or the higher the strain rate is, the smaller the thixotropic strength of the semi-solid alloy.
