Effect of Urea Contents on Pore Structure and Compressive Properties of Ti-10% Mg Porous Materials

With urea as pore-forming agent and by the powder metallurgy method, Ti-10% Mg porous materials were prepared at 630℃ under the condition of vacuum. The pore-forming agent content on the pore structure, physical phase composition, porosity and compressive properties of the products were studied. The results show that when the pore-forming agent content (w) is 25%, the pore sizes of the sintered body are uniform, the main phases are Ti and Mg, and the addition of the pore-forming agent has no obvious effect on the phases; with the increasing of the content of the pore-forming agent, the porosity increases while the compressive strength and elastic modulus decrease; the compressive strength and elastic modulus are 16~183 MPa and 1.87~10.15 GPa, which theoretically can be used as an alternative material for human skeleton.
