Paper Title:
Mechanical Analysis of Semi-Solid Metals Shear Deformation during Compression
  Abstract

Rheological behavior of semi-solid metals during isothermal compression is the most basic forming way for semi-solid die forging. In this paper, based on the metal plastic deformation and high pressure solidification theory, the shear deformation mechanisms of semi-solid metals were analyzed during isothermal compression. Experimental observations and theoretical analyses for AZ91D and composite Al/Al2O3 in the semi-solid state were performed with thermal simulation tests. The results for theoretical analyses and experimental observations show that the shear deformation of semi-solid metals has been realized by metal inhomogeneous flowing from macroscopic view and by grain boundary inhomogeneous migrating from microscopic view respectively during compression.
