英文摘要	ZA92 magnesium alloy was prepared by self-inoculation method(SIM). Refined role of cooling channel on microstructure was studied, and refined mechanism was analyzed. Results show that nucleation in melt were effected by chilling action of cooling channel, flow velocity and shear force of the melt. The suitable slope angle of cooling channel was favorable for liberation and proliferation of the grains.When the melt was flowing on the cooling channel, the microstructure evolution was coarse dendrite→fined dendrite→equiaxed grain→rose crystal→near spherical crystal. Neither smaller nor bigger cooling channel angle was benefitial for refined grain. When cooling channel angel was between 30-45°, the distribution of grain size was more concentrated and smaller, and the average grain size was between 47.5-51.4 μm. © 2017, Materials Review Magazine.
