The results show that, increasing cooling rate, pre-deformation and grain refinement are useful for spreading of the non-equilibriummicrostructure around the primary grains.
结果表明：增加冷却速率、预变形处理和晶粒细化有利于初始凝固组织中存在的非平衡组织的分散细化。

These results indicate that the thermo-stability of fine non-equilibriummicrostructure is tightly related to their history.
