Abstract:China is rich in zinc and less copper. Zn-Cu-Ti alloy as a substitute material for copper alloy，has a series of advantages such as safety， non-toxic，light weight and low price，and has been widely used in machinery manufacturing，automobile manufacturing and other fields. Therefore，it is of great significance to explore the deformation treatment of Zn-Cu-Ti to achieve excellent mechanical properties. This paper combined hot extrusion with multi-pass hot rolling process to prepare Zn-Cu-Ti plates and the influence of deformation treatment on the microstructure and mechanical properties was investigated. After hot extrusion deformation，grain size of the alloy decreases and a fine equiaxed crystal structure was obtained. CuZn5 and TiZn3 second phase particles existed in Zn matrix，and the second phase particles increased after deformation. After rolling deformation treatment，the grains in the microstructure grew up，resulting in uneven distribution of grain size，and the number of the second phase increased with the increase of alloy deformation. After rolling deformation，the tensile strength of the alloy decreased to a certain extent，and the plasticity increased，which was mainly due to the reduction of Cu solution strengthening effect and grain growth in the alloy.
