Titanium powder particles were used as the matrix and powdery urea particles as the space holder to fabricate porous titanium by powder metallurgy technology. And titanium foams with porosity of 42.7~56.2% were prepared successfully. The uniform distribution of the tiny urea particles in the matrix made the titanium foams have homogeneous and connected pore structure. Pore morphology and compressive behavior of the resulting foam have been studied. The pore structure is composed of large pores and small pores distributed on the hole wall, and these small pores are mostly interconnected. Porous regions contained some micro-pores increasing the connectivity of pores. The mechanical behavior was investigated by compressive test, the foams delineated a relatively stable plateau region and the yield strength and Young’s modulus vary in the range of 93.85-276.52Mpa and 1.53-3.21GPa respectively. The results manifested that the processed foams is an ideal medical implant, impact energy absorbing and filterability material.
