Abstract: The texture of 80% cold rolling CuZn ordered alloy was investigated. The development of rolling texturein 50%Cu-50%Zn(at.) alloy has been characterized by a inhomogenous 111 fiber texture with strong 111 <112> component, which is significantly different from the conventional Cu-Zn alloys. The main characters of cold rolling textures in ordered CuZn alloy are obviously similar to that in IF steel with bcc structure or ordered Fe₃Al-based alloys with imperfect B2 structure. From the rolling texture obtained by experiments and simulations,it can be estimated that main deformation mechanism are characterized by the activation of slip systems with <111> Burgers vector in CuZn ordered alloy.
