摘要
以混凝土建筑用30Mn Si PC钢为对象,研究淬火和回火处理对其组织及延迟断裂性能的影响规律。结果表明,当回火温度相同,淬火温度升高,试验钢的抗延迟断裂性能先增后减;当淬火温度为950℃,回火温度为390℃时,试验钢的抗延迟断裂性能最好;当回火温度在430℃,淬火温度在910～990℃时,试验钢的抗延迟断裂性能较好。
Taking 30MnSiPC steel as research object, the microstructures and delayed fracture properties of the test steels were investigated. The results show that, under the same tempering temperatures, when increasing quenching temperatures, the delayed fracture properties of the test steels first increase and then decrease; when quenching at 950 ℃with tempering at 390 ℃, the test steel has the best delayed fracture properties; the test steel has excellent delayed fracture properties when quenched between 910-990 ℃ with tempering at 430 ℃.
