摘要/Abstract

摘要： 通过设计不同淬火温度(240、270、300 ℃)和配分时间(30~300 s)的Q&P工艺,结合显微组织分析、拉伸试验及疲劳测试(轴向力控制法,R=0),系统研究了Q&P工艺对TRIP800钢微观组织及力学性能的影响规律,并对比其与TRIP600钢的疲劳性能差异,以优化高强钢的强韧协同机制。结果表明,最佳Q&P工艺为900 ℃奥氏体化后淬火至300 ℃,400 ℃配分300 s,此时强塑积达13 402 MPa·%,组织为马氏体与均匀分布的残留奥氏体。残留奥氏体含量随淬火温度及配分时间的增加而提升,显著改善塑性但强度降低。在疲劳性能方面,经最佳Q&P工艺处理后TRIP800钢疲劳极限(560 MPa)较TRIP600钢(480 MPa)提高16.7%,恒应变疲劳最大承载能力增加22%,这归因于残留奥氏体的TRIP效应及残留奥氏体与马氏体的协同作用。

Abstract: By designing Q&P processes with different quenching temperatures (240, 270, 300 ℃) and partitioning time (30-300 s), combined with microstructure analysis, tensile tests, and fatigue tests (axial force control method, R=0), the influence of Q&P processes on the microstructure and mechanical properties of TRIP800 steel was systematically investigated. The fatigue property differences between TRIP800 steel and TRIP600 steel were also compared to optimize the synergistic mechanism of strength and toughness in high-strength steel. The results show that the optimal Q&P process involves austenitizing at 900 ℃, then quenching to 300 ℃, followed by partitioning at 400 ℃ for 300 s, achieving a product of strength and elongation of 13 402 MPa·%. When treated by the optimum Q&P process, the microstructure of the TRIP800 steel consists of martensite and uniformly distributed retained austenite. The content of retained austenite increases with the increase of quenching temperature and partitioning time, significantly improving the ductility but reducing the strength. In terms of fatigue property, the fatigue limit of TRIP800 steel treated by the optimum Q&P process (560 MPa) is 16.7% higher than that of TRIP600 steel (480 MPa), and the maximum load capacity under constant strain fatigue increases by 22%, attributed to the TRIP effect of retained austenite and synergistic effect of retained austenite and martensite.
