| Abstract | The Y2O3p/ZG21 composites were subjected to a multi-cross rolling and subsequent annealing and the microstructure, texture and mechanical properties were investigated. The main phase in composites was (W+ Y2O3p) phase but the grain size changed little after trace addition of Y2O3 micro-particles in ZG21 alloy. After rolling, the deformed microstructure with lots of twins and shear bands and a basal texture with double peaks were obtained. The yield strength showed a strong isotropy along rolling direction (RD) and transverse direction (TD). However, after annealing, the deformed microstructure and basal texture were replaced by the recrystallized microstructure and a circle multi-peaks texture. Compared with the rolling states, the yield strength was anisotropic along RD and TD. The anisotropic properties were attributed to the asynchronous change of R-texture component and T-texture component during annealing. The k values of Hall-Petch relationship along RD and TD were also different due to different deformation mechanisms. What's more, the annealed Y2O3p/ZG21 composites still showed superior ductility.
