The Optimization of Chemical Composition and Heat Treatment Parameters for Silicon-Manganese TRIP Steel

    Graphical Abstract
    • Abstract
  • 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.
