从工业化生产的 0Cr19Ni9N奥氏体不锈钢大锻件实物中取样 ,研究了粗大原始组织的高温再结晶。结果表明 ,通过再结晶可得到细小的均匀组织 ,形变储存能越高 ,再结晶温度越低 ,原始组织晶粒越细 ,再结晶温度也越低。而且 ,提高再结晶温度可显著加速再结晶 ,完全再结晶后 ,其强度下降 ,塑性增加 The industrial production of 0Cr19Ni9N austenitic stainless steel forgings in kind sample, the study of the crude high temperature recrystallization. The results showed that the microstructure of the microstructure was characterized by recrystallization. The higher the strain storage energy, the lower the recrystallization temperature, the finer the original microstructure and the lower the recrystallization temperature. Moreover, increasing the recrystallization temperature accelerates recrystallization significantly, and after complete recrystallization, its strength decreases and its plasticity increases
