采用包含滑移、孪晶和再结晶的粘塑性自洽模型，模拟了镁合金AZ 31热轧过程中的织构演变。这种组合模型示出捕捉在机械测试和X射线衍射测量的纹理中观察到的主要特征。该模型在商业有限元程序ABAQUS/Explicit®中实现，并模拟热轧。虽然应变场表现出相当大的梯度，在片材厚度和强烈的剪切成分在片材表面，基底织构，因为它是常见的轧制镁板，占主导地位的整个厚度。
The texture evolution during hot rolling of the magnesium alloy AZ31 is simulated using a visco-plastic self-consistent model including crystallographic slip, twinning and recrystallization. This combined model is shown to capture the main features observed in mechanical tests and in X-ray diffraction measurements of the texture. The model is implemented in the commercial finite element code ABAQUS/Explicit®, and hot rolling is simulated. Although the strain field exhibits considerable gradients over the sheet thickness and strong shear components at the sheet surface, the basal texture, as it is commonly observed in rolled magnesium sheets, predominates over the whole thickness.
