摘要：
Isothermal compression tests on Al-4Cu-Mg alloy were carried out in semi-solid state. Deformation behavior and microstructural evolution are discussed in this paper. Meanwhile, a new constitutive equation, which couples the grain size and liquid volume fraction, has been established for the semi-solid deformation behavior. The results show that the maximum difference between the calculated with the experimental data is less than 15%. The present equation is satisfactory for describing the correlation between the flow stress and microstructure of semi-solid Al-4Cu-Mg alloy. The coupled simulation of the deformation behavior and microstructural evolution during the semi-solid forming would be conducted easily through writing the present equation in a FE code.
