AbstractSolidification temperature range, temperature sensitivity of the solid fraction, temperature process window and phase composition and transformation path of Mg-9Zn-XAl (X=2, 4, 6, wt%) alloys were calculated by Pandat calculation, and studied by experiment. The results indicate that a larger temperature window is conducive to the control and operation of semi-solid forming for the Mg-9Zn-XAl alloy. The temperature sensitivity of all solid fractions is smaller than 0.015. Mg-9Zn-XAl alloys have different transformation temperatures and paths of the phase at different Al additions. alpha-Mg, MgZn, Mg32(Al, Zn)49 and Al5Mg11Zn4 are formed in all samples. When Al addition is increased to 6%, Mg17Al12 phase is formed. The grain size and roundness of Mg-9Zn-XAl alloys prepared by self-inoculation rheo-diecasting method are 65.3, 56.5, 52.2 mum and 1.3, 1.19, 1.23, respectively. When the working temperature is 150 °C, the comprehensive strength and deformation are 278, 283, 295 MPa and 36.22%, 33.02%, 31.21%, respectively.
