工业纯铜的异步冷轧及再结晶织构研究

刘燕声 , 赵骧 , 梁志德

金属学报

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。

COLD ROLLING AND RECRYSTALLIZATION TEXTURE OF CROSS SHEAR ROLLED COMMERCIAL COPPER

LIU Yansheng ZHAO Xiang LIANG Zhide Northeast University of Technology , Shenyang , China

金属学报(英文版)

The texture change along the normal direction to rolling plane of cross shear rolled commer- cial copper has been studied by means of two step method for ODF caleulation and computer simulation.The texture of cross shear rolling of copper is similar in primary components to that of conventional cold rolling,but the scattering degree and direction of the texture are dif- ferent,due to the residual 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.

体心立方金属冷轧织构的电算模拟

刘燕声 , 徐家桢 , 梁志德

材料研究学报

本文采用Taylor 模型,在假设临界滑移系开动几率均等和各滑移系作用简单叠加等条件下,模拟计算了{110}〈111〉,{112}〈111〉,{123}〈111〉滑移系开动时体心立方金属多晶冷轧织构,并与实测体心立方金属多晶冷轧织构取得了较好的一致。
