Porous Ti-5Mo-5Cu Alloy: Preparation, Microstructure and Mechanical Property

摘要

As a new biomedical bone tissue implant candidate, porous Ti-5Mo-5Cu alloy was developed by powder sintering from TiH2, Mo and Cu powders. Space holder material NH(4)HCO(3)granules were added to regulate the pore characteristics like pore morphology and porosity and then mechanical properties including compressive strength and elastic modulus of the porous titanium alloy. The tailored elastic modulus (1.8-6.4 GPa) and compressive strength (93-152 MPa) of porous Ti-5Mo-5Cu alloys with porosity (49.6-61.8%) and average pore size (103-128 mu m) fulfil the preliminary mechanical property and pore characteristics requirements of porous prosthesis. It is expected to be used for hard tissue prosthesis.
