分析了强烈机械搅拌作用对Ａｌ－Ｃｕ１０％合金结晶组织的影响。指出强烈机械搅拌作用下形成的粗大玫瑰状组织和无分枝的颗粒状晶体是由于强烈机械搅拌作用导致液固界面前方形成很薄的溶质原子富集层，使得晶体平面生长，并在生长过程中分枝以粘合方式粗化的结果。
The effect of intensive mechanical agitation on the crystal structure of Al-Cu 10% alloy was analyzed. It is pointed out that the coarse rose-like structure and the unbranched granular crystals formed under intense mechanical agitation are due to the strong mechanical agitation that leads to the formation of a very thin layer of solute atoms in front of the liquid-solid interface so that the crystal plane grows and grows during the growth process The results of cobwelling in the branch.
