摘　　要：对Cu-Cr-Zr系合金铸锭进行热轧、固溶和冷轧,利用X射线衍射仪测试合金材料不同状态下的织构,分析各个状态下的织构种类及其演变规律。结果表明:热轧后材料中主要织构为Copper{112}〈111〉(C)织构、Brass{011}〈211〉(B)织构和S{123}〈634〉织构,存在微弱的立方织构{001}〈100〉;固溶后材料中织构的强度降低,立方织构消失;冷轧后材料中织构的强度随着变形量的增加而强度增加,冷轧过程中主要织构也是C织构、B织构和S织构,在冷轧初期出现Goss{011}〈100〉(G)织构,随后G织构慢慢减弱,直至消失。The Cu-Cr-Zr alloy was treated by hot rolling, solution and cold rolling. The types and the evolution of texture in the different state were investigated using X-ray diffraction. The results show that the main textures of the alloy after hot rolling are Copper{112 } （111）（C）, Brass{011} （211）（B） and S{123} 〈634〉 texture, including the faint cube{001} 〈100〉 texture. The intensity of the texture decreases after solution and the cube texture disappears. In the condition of cold rolling, the intensity of texture enhances with the increasing of the deformation. The main textures during the cold rolling are C, B and S texture. In the early stage of the cold rolling, it appears the Goss{011} 〈100〉（G） texture, then weakening gradually until disappears.
