XING Shu-qing , CHEN Zheng-zong , MA Yong-lin , LI Hui-qin

钢铁研究学报(英文版)

The effect of refined precipitations and dispersed phases on the toughness of SS400 steel was investigated by rapid tempering with thermomechanical simulation tester, and the electromagnetic induction rapid tempering process was simulated. The conventional tempering and rapid tempering process were ...

钢铁

研究了攀钢新钢钒公司生产帘线钢72A过程中钢中氮含量变化对钢中TiN夹杂析出的影响。研究发现,随着钢中氮含量的升高,钢中析出的TiN夹杂数量变多,尺寸变大。热力学研究表明,在帘线钢中TiN一般只能在固相区形成,考虑元素偏析对凝固前沿元素富集的影响,凝固过程中TiN能在固液两相区析出。在帘线钢生产过程...

钢铁

对16Cr14Co12Mo5耐热耐蚀轴承钢在1050℃高温淬火后,在490~540℃两次回火后的组织性能以及强韧化机制进行研究。结果表明:随着回火温度的升高,抗拉强度Rm逐渐增加,最大时超过了1900MPa,屈服强度Rp0.2在500℃回火后达到1400MPa,随后逐渐减小;断面收缩率和伸长率略有减...
