| 摘 要： | 研究了CSP热轧低碳SPHC钢的微观组织、第二相粒子的析出及其对强度的影响,对马钢CSP生产的SPHC钢和常规热轧工艺的SPHC钢进行了屈服强度比较.结果表明,马钢SPHC钢的实测值比计算值高42MPa,常规工艺生产的SPHC钢实测值与计算值比较接近.对马钢SPHC钢进行透射电镜观察,观察到其中存在纳米级的、亚微米级的和微米级的3种尺寸级别的第二相粒子,马钢SPHC钢沉淀强化的强度增量为40 MPa. |

| Abstract: | The effect of microstructure,precipitation of second phase on strength of SPHC produced by CSP(compact strip production) were investigated.The yield strength of SPHC produced both by CSP and by traditional technology were compared.The results show that the calculated yield strength of SPHC produced by CSP is 42 MPa lower than measured,but the measured and calculated yield strength of SPHC produced by traditional technology are the same.The TEM observation shows that there are three kinds of particles which sizes are nano-scale,submicron-scale,and micro-scale in the steel produced by CSP.Precipitating strengthening contributes 40 MPa to the yield strength of SPHC produced by CSP. |
