摘要： 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.

Abstract: The effect of cross-shear rolling on the cold-rolling and recrystallized texture of IF (interstitial-free) steel was studied, where the rules of simulated shearing strain changing with the ratio of speed of rolls are applied to the texture simulation based on Taylor model to analyze the effect of shearing strain Εxz on texture deformation. The results showed that after cold rolling the componential α fiber texture decreases gradually and γ fiber texture increases slightly with increasing ratio of asynchronous rolling speeds. And the fact is mainly resulting from the additional shearing strain during cross-shear rolling. The formation of {111}<uvw> recrystallization nucleus was found in no relation to the {001}<110> component. Moreover, the volume percentage of recrystallized {111}<112> component resulting from asynchronous rolling is obviously higher than that resulting from synchronous rolling. This is because the volume percentage of {111}<112> component resulting from cold rolling is obviously higher than that resulting from synchronous rolling.
