The key to fining the structure of ingot casting lies in the formation of a number of fine equiaxed crystal grains. 金屬鑄態(tài)組織細化的關(guān)鍵是獲得大量細小等軸晶。
The results show that the as-deposited microstructure possesses the feature of whole equiaxed grains and fine distributed micro cavities on the grain boundaries. 沉積態(tài)高鎂鋁合金基體呈全部等軸晶組織并存在少量顯微孔洞是沉積態(tài)組織的主要特征。
