Paper Title:
Rheological Behavior of Semisolid Al-6.5wt%Si Alloy at Transient State
  Abstract

In the present work, the rheological model for semisolid metal slurries (SSMS) is constructed and then applied to the Al-6.5wt%Si alloy to investigate its rheological behavior at transient state during isothermal shearing and isothermal resting. Firstly, the present study shows that the agreement of the variation of viscosity and the average agglomerate size with shearing time and resting time shows that the microstructure of SSMS determines its rheological behavior. Secondly, the deagglomeration of particles is about two orders of magnitude faster than agglomeration, which is in agreement with the experimental measurement. Finally, the Al-6.5wt%Si alloy at transient state has the behavior of “shear-thinning”, but not “shear-thickening” predicted in the documents.
