【Abstract】 A semi-solid casting and rolling experimental apparatus, which can be used to obtain semi-solid materials and form through semi-solid casting and rolling, have been developed. The semi-solid casting and rolling forming processes of AZ91D magnesium alloys were studied by using of tests, and observed the microstructures and morphologies of samples. The results showed that the semi-solid casting and rolling technologies of magnesium alloys could be applied to improve the safe protection level during high temperature casting processes of magnesium alloys and change the present situation of bigger deformation force being needed during deformation processes of magnesium alloys.更多还原
