| Abstract: | The microstructure evolutions during spray forming process for high magnesium aluminum alloy are investigated in this paper. The results show that the as-deposited microstructure possesses the feature of whole equiaxed grains and fine distributed micro cavities on the grain boundaries. The formation mechanism of equiaxed grains and micro cavities during spray forming process are discussed. |
