摘　　要：对3种不同热轧终轧温度下得到的Ti+Nb处理的高强IF钢板组织和性能进行了试验室研究。试验结果表明，随着终轧温度的降低，γ纤维织构增强，值增加，而退火组织的平均晶粒尺寸无显著变化，塑性保持不变，屈服强度稍有降低。The structure and property of Ti+Nb treated high str ength interstitial free (IF) steel sheet hot rolled with three different finishe d temperature have been studied in laboratory. The experimental results showed that with decreasing the finishing temperature the γ fiber texture enhan ced, the value increased, and the plasticity of steel annealed didn't changewith no appreciable change in average grain size of structure, but the lower yie ld strength decreased slightly.
