Abstract
An analytical model of apparent viscosity was built up based on analysis of energy
dissipation during rheocasting. By study the evaluation law of microstructure analyzed with a
quantitative metallographic analysis system for semi-solid alloys, the variation law of apparent
viscosity with time has been obtained. The model was verified in the experiment of A356 alloys with
a coaxial double-bucket rheometer, and the results of simulated experiment and theoretical
calculation are in a good agreement.
