研究了82B、72B和57B钢丝的拉拔与球化退火过程中组织与力学性能变化,探讨了化学成分与工艺参数对球化退火过程的影响。研究结果可为不同成分的高速线材的球化退火工艺提供必要的参考。
The changes of microstructure and mechanical properties during the drawing and spheroidizing annealing of 82B, 72B and 57B steel were investigated. The effects of chemical composition and process parameters on the spheroidizing annealing process were discussed. The results can provide the necessary reference for spheroidizing annealing of high-speed wire with different compositions.
