本文介绍了一种金属晶粒细化的新工艺，即利用金属本身已有的非自发形核潜力，使Al，Cu，Sb晶粒细化探讨了金属自身激冷薄片的冷却速度、加入量、保温时间对晶粒细化效果的影响.Al的自身细化效果与加入适量的Al-Ti-B中间合金相当；Cu和Sb的自身细化效果良好.根据金属遗传原理探讨了晶粒自身细化机理.
In this paper, a new process of metal grain refinement is introduced. By using the existing non-spontaneous nucleation potential of the metal itself, the grain refinement of Al, Cu and Sb is discussed. The cooling rate of the metal self- , Holding time on the effect of grain refinement.Al refining itself and adding the right amount of Al-Ti-B master alloy equivalent; Cu and Sb self-refining effect is good.According to the metal genetic theory to explore the grain itself Refinement mechanism.
