Abstract:The rheological behavior of semi solid Al Si alloy in the solid liquid zone has been investigated with the high temperature static shear testing rheometer. The rheological parameters of semi solid Al Si alloy have been measured. The relationships between the rheological parameters and temperature have been studied. The rheological model and the stress strain equation of the intrinsic behavior have been illustrated, and the process of evaluating rheological parameters has been mentioned.

Key words: semi solid Al Si alloy solid liquid zone rheological property
