| 摘 要： | 研究了1Cr18Ni9Ti奥氏体不锈钢加工硬化时组织的演变过程及其对性能的影响。结果表明，冷变形可提高钢的各种强度性能指标，尤其大大改善疲劳性能。经60％变形后，钢的疲劳强度提高了65％左右。随着加热保温时再结晶过程的进行，钢的强度下降而塑性逐步恢复。

| Abstract: | The structure evolution and the effect of structure on properties of 1Cr18Ni9Ti austenitic stainless steel were studied.The results show that cold deformation can largely raise the mechanical properties of the steel,especially the fatigue property.Compared with non-deformation steel,the fatigue stress of 1Cr18Ni9Ti austenitic stainless steel after 60% cold deformation is raised about 1.65 times.With the development of recrystallization,the strength of the steel decrease and the plasticity resume gradually. |
