Abstract

Abstract

Using pure Ti powder and Ti(C_0.5N_0.5) particles as raw materials, Ti(C_0.5N_0.5) particle reinforced Ti matrix composites were prepared by powder metallurgy process. The effects of Ti(C_0.5N_0.5) content on the microstructure and mechanical properties of titanium matrix composites were studied. The results show that the addition of Ti(C_0.5N_0.5) particles significantly refines the grain size of Ti matrix, and the grain morphology changes from coarse columnar grain to fine equiaxed grain. With the increase of Ti(C_0.5N_0.5) content, the porosity of Ti matrix composites decreases obviously, the density increases, and the hardness and yield strength of Ti matrix composites increase gradually, but the compressive strain decreases gradually.
