随着晶粒尺寸的减小,材料的屈服极限和弹性模量均产生的明显降低。由于晶粒尺寸未达到临界尺寸,在模拟中仅观察到了反Hall-Petch关系。
With the decrease of grain size, the yield limit and elastic modulus of the material are obviously reduced. Because the grain size does not reach the critical size, only the anti-Hall-Petch relationship is observed in the simulation.
