Study on Apparent Viscosity of Semi-Solid Alloys during Rheocasting

Abstract:

Article Preview

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.
