研究了异步轧制对IF钢的冷轧及再结晶织构的影响,并且将模拟的剪切应变随辊速比的变化规律应用到以Taylor模型为基础的织构模拟中,分析了剪切应变εxz值对形变织构的影响.结果表明:随着异步轧制速比的增加,冷轧的α纤维织构组分逐渐减少,γ纤维织构组分稍有增加.异步轧制时,附加的切应变是造成这种变化的主要原因;{111}〈uvw〉再结晶晶核的形成与{001}〈110〉织构组分无关.异步轧再结晶{111}〈112〉织构组分体积分数明显多于同步轧,这是由于在冷变形状态下,{111}〈112〉织构组分就明显高于同步轧制条件.
The influence of asynchronous rolling on the cold rolling and recrystallization texture of IF steel was studied. And the law of shear strain and roll speed ratio was applied to the texture model based on Taylor model. The effects of shear The results show that the α-fiber texture components of cold-rolled steel decrease gradually and the γ-fiber texture components increase slightly with the increase of the asynchronous rolling speed ratio.In the case of asynchronous rolling, The additional shear strain is the main reason for this change. The formation of {111} recrystallized nuclei is not related to the {001} <110> texture components. The volume fraction of the component is significantly more than the synchronous rolling, which is due to the higher {111} <112> texture components than the synchronous rolling conditions in the cold deformation state.
