摘要
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 。
The specimens were taken from forged 0Cr19Ni9N stainless steel which was industrially produced. Recrystallization of the steel was investigated. The results have shown that fine and uniform microstructure can be obtained from original coarse grain size through recrystallization.The higher the stored energy by deformation, the lower the recrystallization temperature. The finer the original grain size, the lower the recrystallization temperature. Increasing recrystallization temperature can greatly enhance the process of recrystallization and result in decreasing strength and increasing ductility.
