英文摘要	A noval high zinc-content Mg-9Zn-2Al magnesium alloy semi-solid slurry was prepared by self-inoculation method (SIM). The effect of melt treatment temperature on the microstructure was investigated when the addition of self-inoculants is 5% (mass fraction) and the angle of fluid director is 45°. The melting state of the inoculants was analyzed. Furthermore, the mechanism of the primary inoculation was discussed from the standpoint of atomic cluster. The results show that the average grain size increases when the melt temperature is excessively low or high. In temperature range of 695-710°C, the average grain size is smaller, about 47.5-48.8 μm. In SIM casting, a proper melt treatment temperature can be determined by the derived formula, which is the temperature of the inoculants in the entrance of fluid director. Meanwhile, the solid phase ratio fS is put forward to describe the case of inoculants' melting.
