摘要
本文测定了14MnNbRE钢中微细析出相粒子化学成分;研究了析出相粒子直径及形状因子频数分布、终轧温度对析出相粒子直径和形状因子均值及标准差的影响和屈服强度增量与析出相粒子平均直径的关系,探讨了(Nb.Ti)(C,N)与A1N微细析出相复合粒子的形成机制和析出相粒子的强化作用机制。
The chemical composition and distribution of the diameter and shape factor of the precipitation particles in control-rolled 14MnNbRE steel have been determined. The influences of finish rolling temperature on the mean value and standard deyiation of the diameter and shape factor of the precipitation particles and the relationship between Δσ_s and the mean diameter of the precipitation particles have been studied. The formation mechanism of precipitating compound particles of (Nb, Ti)(C, N)and AlN and the strengthening mechanism by the particles have been discussed.
