Abstract: The magnesium alloy, as an important structure material, provided the light density, high specific intensity, good damping and excellent electromagnetic shielding properties have attracted more extensive attention. However, the poor deformation ability of magnesium alloys has greatly limited its industrial application. In this paper, the traditional casting method was used to obtain the ATZ331 alloy which was plastic deformed by uniaxial rolling and cross rolling, and the metallographic microscope, SEM, XRD and universal material tester were used to character the microstructure evolution and mechanical properties. The results showed that the ATZ331 alloy treated by solid solution caused the fine and dispersedly distributed Mg2Sn and MgZn particles were precipitated at the grain boundary and within the grain of matrix α-Mg and the mechanical properties of ATZ331 alloy were improved by dispersion strengthening mechanism. The rolling methods have great influence on the microstructure and mechanical properties of ATZ331 alloys. The tensile strength of ATZ331 series alloy deformed by uniaxial rolling reached 222 MPa and the elongation was 18%, lower than cross rolling.
