摘要
本文采用正交设计及方差分析法，对获取良好ＴＲＩＰ效应的Ｓｉ、Ｍｎ系低碳低合金钢化学成分及热处理工艺进行了优化。结果表明：化学成分为０．２８％Ｃ－１．６２％Ｓｉ－１．０９％Ｍｎ的钢，经等温淬火工艺７９０℃×４ｍｉｎ→４００℃×３ｍｉｎ处理后，获得最佳综合机械性能，强塑积达３２２．３３ＭＰａ·％。
Orthogonal design and variance analysis methods have been used to optimize chemical composition and heat treatment parameters for good TRIP and combination of elongation and tensile strength in low carbon low alloy silicon-manganese steels. As a result, the optimum chemical composition and heat treatment parameters have been found, an excellent combination of elongation and tensile strength(TS ×T-EL=322.33 MPa·%) has been achieved in 0.28%C-1.62%Si-1.09%Mn steel at an isothermal holding temperature of 400℃ for 3 min after heating at 790℃ for 4 min.
