Working the metal cold is done with the aim of obtaining a more accurate finish. 对金属进行冷加工是为了得到更精确的光洁度。
This is a method of reliving the internal stress set up in steel during forming, cold working, and cooling after welding or machining. 这是消除内应力的一种方法,内应力是在钢铁的成形中,冷加工中,焊接或切削后的冷却中产生的。
This could be attributed to the formation of high-density dislocations and vacancies during cold deformation, which provided a high diffusion path of carbon atoms. 其原因是在冷变形过程中产生了高密度位错以及大量空位等缺陷,为碳原子的扩散提供了高速率扩散通道,促进了碳原子的扩散。
