摘　　要：Porous Ti for the application in clinic orthopaedics field was manufactured by powder metallurgy technique using polymethyl methacrylate as the space holder under different sintering conditions.The final morphological features and mechanical properties were described.The results show that the increase of sintering temperature and time leads to improved grain size of porous Ti ligament and decreased pore size,with a concomitant increase of tensile strength and elastic modulus.The microstructure and mechanical properties of solid Ti depend more on the sintering temperature and time than those of porous Ti.The relative contributions of these mechanisms of porous Ti vary with the initial microstructure and oxygen content.

关 键 词：porous Ti  powder metallurgy  microstructure  mechanical property
