英文摘要	Semi-solid microstructure of ZA96 magnesium alloy was prepared by self-inoculation method (SIM). The effects of self-inoculation technological parameters on the microstructure of semi-solid ZA96 magnesium alloy were investigated. And the nature of interactive effect between technological parameters was analyzed from the standpoint of temperature field. The results show that high-quality semi-solid billets and slurry can be obtained by SIM. The effects of self-inoculation technological parameters on the microstructure of semi-solid billets are bigger, but for the microstructure of semi-solid slurry which is collected from the exit of the fluid director and holding in semi-solid interval, the effect of self-inoculants is smaller, but that of the angle of fluid director is bigger. When the superheat of the melt is 80-95 °C and the addition of self-inoculants is 5% and the angle of fluid director is 45°, the grain size of semi-solid billet is 35.6 μm; or after holding 20 s at 552 °C, the grain size of primary phase is 45μm and the roundness is 1.7. The interactive nature of self-inoculation technology parameters is to control nucleation by coordinating them. The formula between the temperature of melt in the exit of fluid director and self-inoculation technological parameters was derived.
