摘　　要：研究了汽车转向节锻后余热淬火工艺对钢的组织和性能的影响。结果表明 ,锻造余热淬火工艺对汽车转向节质量有明显改善。余热淬火可以保留变形造成的位错增殖和晶粒细化 ,从而使材料具有高的强度和韧性。The effect of thermomechanical treatment on the microstructure and properties of the automobile steering knuckle was researched in this paper.The results show that the thermomechanical treatment can improve the quality of the automobile steering knuckle.The reproduced dislocation and refined grain created during the deformation can be remained in the steering knuckle after thermomechanical treatment,this makes the steering knuckle have high hardness and good ductility.
