摘　　要：研究了大变形后弹簧钢丝在不同温度下退火过程中的组织及性能变化。结果表明:拉拔态65Mn弹簧钢球化退火过程中,在保温时间一定的情况下,随着退火温度的升高,其抗拉强度逐渐降低,断面收缩率逐渐升高。球化退火后的组织形貌与钢丝拉拔变形方向有关。The microstructure and properties of spring steel wire annealed at different temperatures after large deformation were studied.The results show that during spheroidization annealing of 65Mn spring steel with the constant holding time,the tensile strength decreases gradually and the shrinkage of the section increases along with the increase of annealing temperature.The morphology of spheroidized annealing structure is related to the direction of deformation of steel wire.

关 键 词：弹簧钢丝 球化退火 塑性变形 拉拔 方向
