摘　　要：分析了超高强度奥氏体不锈钢丝在多道次拉拔过程中的组织变化。结果表明,当拉拔变形量大于30%时,组织中开始出现形变马氏体,且变形量越大形变马氏体数量越多,尺寸越小。并分析了拉拔时产生形变马氏体的原因。The microstructures change of super-high strength of austenite stainless still silk in multi-ply drawing were analysed.The results show that when the deformation degree excess 30% the deformation martensite can be found in the microstructure, and the greater deformation degree the more content of deformation martensite,and the smaller size of martensite grain.The reason of deduces deformation martensit in the drawing process is analysed also.
