摘　　要： 研究了铁素体区热轧压下率和润滑条件对一种Ti-IF钢的热轧后退火钢板的力学性能的影响以及润滑条件对再结晶织构的影响。结果表明,随铁素体区压下率的增加,采用润滑轧制时Ti-IF钢的成形性能提高;另一方面,随润滑条件的改善,成形性能得到提高,而其他力学性能变化不大。织构分析表明,采用润滑轧制,可以减少试样沿厚度方向的<110>∥ND剪切织构,有利于<111>∥ND织构的生成,使有利织构的强度大大增加,因此提高了IF钢的成形性能。 The effects of hot rolling reduction in ferrite range and lubrication condition on the properties and recrystallization texture of Ti-IF steel strip were studied. It was observed that the formability is improved with increase of hot reduction rate in case of lubricated rolling, also enhanced with the improvement of lubrication conditions, while no distinct changes were found in other mechanical properties. It was clear from the texture analysis that the unfavorable 〈 110〉///ND shear texture can be reduced to form favorable 〈 111〉///ND texture by lubricated hot rolling in ferrite region and formability of IF steel is improved.
