摘要：

To satisfy the mechanical requirement of porous bone substitutes, the porous Ti with the porosity in the range of 55-75% was fabricated using the space-holder sintering process. The pore size is in the range of 200-500 mu m, and the mean value is 410 mu m. The mechanical properties were investigated by the compressive test. Results show that the plateau stress and Young's modulus are in the range of 10-35 MPa and 3-6.4 GPa, respectively. The relationship between the mechanical properties and the relative density of porous Ti is found to obey a power law relation. The strength of the porous Ti is mainly affected by the density. The typical rupture section of compressed samples has the V-shape. (C) 2008 Elsevier B.V. All rights reserved.
