摘　　要：采用X射线衍射仪分析IF钢铁素体区热轧织构以及退火织构的演化,在实验室热轧机上进行了IF钢的铁素体区热轧,研究了摩擦对IF钢铁素体区热轧、退火织构的影响。结果表明:无润滑轧制时,钢板表层形成强高斯织构组分{110}〈001〉,弱γ纤维织构,导致再结晶织构中高斯组分强度高,γ纤维织构强度低;润滑轧制时,钢板表层高斯织构组分强度降低,{100}〈011〉、γ纤维织构强度提高,退火后γ纤维织构强度提高。钢板中心受摩擦作用影响较小,轧制过程中发展为较强的α和γ纤维织构,退火后γ纤维织构成为主要织构组分。The texture evolution of IF steel during hot rolling in ferrite region and subsequent annealing was analyzed with X-ray diffract.The IF steel plates were rolled using hot mill in laboratory,and the effect of friction between steel sheets and rolls on texture characteristics during hot rolling in ferrite region and subsequent annealing were investigated.The results show that in the case of hot rolling without lubrication,the strong {110}〈001〉 texture and weak γ-fiber texture at surface are formed,which induces strong {110}〈001〉 texture after recrystallization annealing.During hot rolling with lubrication,the intensity of {110}〈001〉 component at surface decreases,but {100}〈011〉 and γ-fiber components increase.So the γ-fiber components increase after annealing.Owing to low friction effect,the center region of steel sheet is full of well-developed α and γ fiber textures during hot rolling process in ferrite region,and the γ fiber become main texture components after annealing.
