THE SETTING UP RHEOLOGIC MODEL OF ALUMINUM ALLOY IN QUASI-SOLID
Al 合金准固态的流变学建模

On the basis of the rheologic theory and system identificationthe problem on setting up rheologic models of aluminum alloys in quasi-solidis investigated.The microcomputer and rheologic shear apparatus were applied.The processes of setting up the rheologic model and constitutive equationsand estimating the model parameters are shown for Al-5.14% Cu alloy.
