摘要：

研究了中后帮机零部件用铁素体不锈钢的成形性能，分析了Ti元素对冷轧态和退火态铁素体不锈钢的组织与性能的影响，并分析了其作用机理。结果表明，Ti元素的添加可以抑制铁素体不锈钢再结晶晶粒长大，也有利于不锈钢形成γ纤维织构；未添加Ti的不锈钢和添加Ti的不锈钢在0°，45°和90°方向上的硬化指数差别不大，添加Ti的不锈钢强度系数及在同一方向上的塑性应变比要比不添加Ti的不锈钢高；Ti元素的添加在铁素体不锈钢中形成了Ti（N,C）颗粒，可以起到抑制形核和细化再结晶晶粒的作用。

The forming performance of ferritic stainless steel for heel seat and side lasting machine was investigated, and the influences of Ti on the microstructure and properties of ferritic stainless steel under cold rolled and annealed states were studied. Furthermore, its forming mechanism was also analyzed. The results show that the addition of Ti can inhibit the recrystallization grain size of ferrite stainless steel, and is beneficial to the formation of γ fiber texture. However, the hardening exponents in the directions of 0°, 45° and 90° have little difference when stainless steel with and without Ti, and the strength coefficient and plastic strain ratio on the same direction of stainless steel with Ti are higher than that of stainless steel without Ti. Thus, Ti (N, C) particles are formed in the ferrite stainless steel with Ti, and they play a role in the inhibition of nucleation and refinement of the grain.
