Microstructure evolution and constitutive modeling of as-cast A356 aluminum alloy in semi-solid deformation regime by A.H. Boluri Gashti, H.R. Abedi, M.T. Salehi

“…Under these conditions, the specimens were deformed up to the high strain level (>0.5) without creating cracks or tearing under very low stresses less than 2 MPa. A phenomenological-physical constitutive equation was also developed considering deformation parameters (temperature, strain rate, and strain) and material's parameters (grain size, strain rate sensitivity, viscosity) which was capable of predicting the semisolid flow stress behavior of the material.…”
