| 中文摘要: |
| 针对奥氏体不锈钢在冷加工和热处理过程中发生相变，并容易被腐蚀的情况，通过实验验证了奥氏体不锈σ在
冷加工过程和热处理过程中的相变方式，以及不同组织对其耐腐蚀性的影响。通过冷加工变形试样制备、高温回火、金
相分析、扫描电子显微镜下观察和能谱分析，分别对马氏体和o相相变的机理进行验证。通过金相腐蚀试验，分别对2
种相存在条件下材料的耐腐蚀性能进行比较。结果表明冷加工变形下产生的马氏体，会在一定程度上降低材料的耐腐
蚀性能，而高温回火产生的σ相对材料耐腐蚀性的影响更为明显。 |

| Based on the condition of austenitic stainless steel with phase transformation and easy corrosion during cold
machining and heat treatment process, the phase transformation of austenitic stainless steel during cold machining and
heat treatment process was proved, and the effects on corrosion resistance of metastable austenitic stainless of different
metallurgical structures was verified by the experiment. Mechanism of martensitic andσ phase transformation was
verified by sample preparation under cold machining, high temperature tempering, metallographic analysis, observation
under SEM and energy spectrum analysis. The corrosion resistance of the material under the existence of martensitic and
(σ phase was compared by the metallographic corrosion experiment. The results show that martensitic which is produced
under cold machining reduces the corrosion resistance of the material to a certain extent. while the effect of the(σ phase
which is produced under high temperature tempering on corrosion resistance of the material is more obvious. |
