| 摘 要： | 通过在600,630,680,700和720℃保温1 h空冷,以及在630℃短时时效后炉冷和空冷的热处理,研究了不同时效温度、时效时间以及冷却方式对沉淀硬化马氏体不锈钢FV520B的组织和力学性能的影响.结果表明,630℃短时时效后钢中即可析出一定量的逆转变奥氏体,且钢中的析出相尺寸较小并弥散分布,由此提出了一种沉淀强化马氏体不锈钢的热处理工艺优化,即FV520B钢经630℃短时时效并炉冷后.可以获得较佳的高强度和高韧性组合.

| Abstract: | Low carbon martensitic precipitation hardening stainless steels are widely utilized in many engineering applications due to their high strength with reasonable toughness,ductility and corrosion resistance.However,those properties and their combinations are not always satisfactory to their users.For further improvement of the mechanical properties of these types of steels,a fundamental understanding of the detailed microstructural features with various aging conditions is necessary. Therefore,the effects of ... |
