| 摘 要： | 研究了脉冲电流对一种冷加工黄铜再结晶组织和力学性能的影响，结果表明，利用脉冲电流作为形变黄铜的再结晶处理手段，可以得到比常规退火处理更细更均匀的再结晶晶粒，从而使该材料的综合力学性能提高，脉冲电流作用时间短，加热速度快、促进再结晶形核和抑制随后晶粒长大是得到细晶粒的原因。

| Abstract: | Recrystallized microstructure and mechanical properties of cold worked brass annealed by electropulsing and routine annealing were studied. The result shows that finer and more even recrystallized grains can be obtained by using electropulsing than routine annealing, and mechanical properties of the material can be improved. The characteristics of electropulsing of very short treating time, high heating rate, increasing nucleation and retarding the subsequent rate of grain growth are the main factors producing finer recrystallized grains. |
