采用Taylor类型多晶体塑性变形模型, 模拟了初始自由分布和近似立方织构多晶铝的轧制织构演变. 应用取向线分析方法将不同模型的理论计算结果进行了系统分析, 并与实测轧制织构进行了比较. 结果表明: 在低轧制变形程度时, 完全限制(FC)模型计算结果的取向分布较其它模型更符合实际结果. 在较高程度轧制变形时, 对于初始自由分布的多晶铝轧制试样, lath模型与实验符合较好;而对于初始具有近似立方织构的样品, 使用混合模型结果较佳.
The rolling texture evolution with initial randomly distributed texture and nearly cube texture was simulated by Taylor-type models. A systematic comparison of the theoretical results obtained by the different type models against the experimental rolling textures is performed by orientation line analysis. The results shows that the orientation distribution calculated by the FC Taylor is closer to experimental results than those by other models at the low rolling deformation degree. During the higher deformation degrees, the results by the lath model agree the measured better for the initial randomly distributed texture while the simulated results obtained by the mixed are closer to the measured than those by the other models for initial cube texture.
