如图4.2所示，晶粒流动的方向就是在塑性变形期间结晶排列的方向。

As shown in Fig. 4.2, grain flow is the direction of the pattern that the crystals take during plastic deformation.

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。

The results show that, increasing cooling rate, pre-deformation and grain refinement are useful for spreading of the non-equilibrium microstructure around the primary grains.

动态再结晶晶粒尺寸随着变形温度的升高而增大，随着应变速率的升高而减小。

The dynamically recrystallized grain size increases with increasing deformation temperature and reduces with increasing strain rate.
