摘要
采用正交试验方法对高速铁路用新型弹簧钢的热处理制度进行了系统研究。结果表明 :经 90 0℃保温 30 min油淬火及 380℃下保温 6 0 min回火处理 ,该合金可以获得保持马氏体形貌的屈氏体组织 ;在此热处理制度下 ,弹簧钢的强韧性最佳 ,屈服强度达到 1785 MPa,伸长率和断面收缩率分别达到 11.5 %和 39%。
The heat treatment of a new type spring steel for high-speed railway application has been systematically investigated. The experimental results show that the satisfied microstructure of this steel could been obtained by austenitzing at 900 ℃ for 30 minutes and tempering at 380 ℃ for 60 minutes. in this way, the optimum yield strength and toughness, could been obtained.
