Abstract Cube texture extensively influences the physical and mechanical properties of materials, but the {100} cube texture scarcely occurs in body-centered cubic metals as deformed state. The cube texture formation in low carbon steel bars processed via 24-pass warm bi-axial rolling (WBR) was confirmed. The cube texture was observed in the area from the center to the quarter in the 13 mm rolled square bar, and it disappeared near the surface. In the present study, the cube texture formation was studied from the viewpoint of strain and deformation mode through finite element analysis (FEA). An equivalent strain, eeq, accumulated, and strain components inside a bar during 24-pass rolling were quantified by using FEA. The eeq was efficiently accumulated in the center and it was more than twice as large as the nominal strain calculated from shape change. The area from the center to the quarter was alternately compressed from two directions under the simple compressive mode. On the other hand, the surface area was compressed under the plane strain mode and shear deformation. Consequently, the bi-axial simple compressive mode brings out cube texture. These quantitative strain and deformation mode analyses would be useful for creating materials with cube orientation.

应变和变形模式对温双轴轧低碳钢立方织构形成的影响

摘要 立方体织构广泛地影响材料的物理和力学性能，但{100}立方体织构在体心立方金属中很少出现变形状态。证实了通过 24 道次温双轴轧制 (WBR) 加工的低碳钢棒材的立方织构形成。13mm轧制方棒从中心到四分之一的区域观察到立方体纹理，在靠近表面处消失。在本研究中，通过有限元分析（FEA）从应变和变形模式的角度研究了立方体纹理的形成。在 24 道次轧制期间，棒材内部的等效应变、eeq、累积和应变分量通过使用 FEA 进行量化。eeq 有效地累积在中心，它是根据形状变化计算出的名义应变的两倍多。从中心到四分之一的区域在简单压缩模式下从两个方向交替压缩。另一方面，在平面应变模式和剪切变形下，表面积被压缩。因此，双轴简单压缩模式带出立方体纹理。这些定量应变和变形模式分析对于创建具有立方体取向的材料非常有用。
