本文采用不完整极图二步法测算ODF与计算机模拟相配合,研究了工业纯铜的异步冷轧织构沿轧板厚度方向的变化规律,同时也对冷轧试样的再结晶织构沿该方向的变化进行了探讨。结果表明,Cu的异步冷轧织构与普通冷轧织构在主要织构组份上大体相同,但在轧板厚度方向不同位置处,因残余切应变不同而导致织构的漫散程度和方向有所差异。异步轧制过程中的切应变对再结晶织构形态没有影响。
The texture change along the normal direction to rolling plane ofcross shear rolled commercial copper has been studied by means of the two-stepmethod for ODF calculation and computer simulation. The texture of cross shearrolling of copper is similar in primary components to that of conventional coldrolling, but the scattering degree and direction of the texture are different due to theresidual shear strain change in different position along the normal to rolling plane.It seems that no more effect of the shear strain upon the recrystallization texture.
