| 摘 要： | 通过对Cr17含Ni马氏体不锈钢热处理工艺试验，研究了不同的淬火和回火温度对Cr17含Ni马氏体不锈钢（低、高倍）组织和力学性能的影响。试验结果表明：经过淬火＋高温回火处理后，材料晶粒明显细化，材料的综合力学性能得到最大提高。同时，在中温回火时，材料的强度和硬度有所提高，塑性和韧性略有降低，出现明显的中温回火脆性倾向。Cr17含Ni马氏体不锈钢的使用状态组织为索氏体，具有良好的耐蚀性能，又具有较高的强度和韧性配合。

| Abstract: | On the basis of a series of heat treatment tests, the effect of different quenching and tempering temperatures on the macro and micro structures and mechanical properties of Cr17 ＋ Ni martensitic stainless steel was investigated. The test results indicate that after quenching and high- temperature tempering, the material＇ s grain will be obviously finer, and its comprehensive mechanical properties will be greatly improved. Meanwhile, with the medium-tempering treatment, the material＇ s strength and hardness will be enhanced, but its plasticity and flexibility will be decreased a bit, and it also has an obvious medium-tempering embrittlement trend. The service state structure of Cr17 ＋ Ni martensitic stainless steel is sorbitic, which has an excellent anti-corrosion performance and a better combination of strength and toughness. |
