摘 要：Porous Ti samples were fabricated by powder metallurgy technique using three kinds of Ti powder and the space holder of polymethyl methacrylate.The final morphological features and mechanical properties were described.Results show that there is only a-Ti phase in porous Ti samples.After sintering,the oxygen content of three porous Ti is increased from the range of 0.34–0.63 wt% to 0.95–1.3 wt%.The porous Ti prepared from the uneven powders with an average particle size of（22.75±11.09） lm presents the largest micro-pore size,grain size,and oxygen content,which lead to the lowest strength and Young’s modulus.
