Abstract

The microstructure and texture of different rolling processes in situ Cu–15Cr sheets are studied. The results show that the second phase Cr in the material gradually become broken, flattened, merged and homogenized from dendritic state to oriented thin lath. Meanwhile, the texture in distributed copper matrix grains finally forms Brass {110}<112>, Goss {001}<110> and Copper {112}<111> textures along with Cr phase texture of randomly distributed α-fiber (<110> fiber) and γ-fiber (<111> fiber) texture. Based on VPSC (visco-plastic self-consistent model), the texture of cold rolled Cu–15Cr composite is simulated, and the simulation result indicates that obvious twinning effect in the copper matrix appears with a feature of a special texture evolution law of Goss.

Cu-15Cr原位复合材料轧制板的组织和织构演变

摘要

研究了原位Cu-15Cr轧制过程中不同轧制过程的组织和织构。结果表明，材料中的第二相Cr从树枝状转变为定向薄板条，逐渐破碎，变平，融合和均质化。同时，分布的铜基晶粒中的织构最终形成黄铜{110} <112>，高斯{001} <110>和铜{112} <111>织构以及随机分布的α纤维（<110>纤维）和γ纤维（<111>纤维）织构。基于粘塑性自洽模型，对冷轧Cu-15Cr复合材料的织构进行了仿真，仿真结果表明，铜基体中出现了明显的孪生效应，具有高斯特殊的织构演化规律。 。
