Microstructure formation of porous sintered Ti-Si-Zr compacts with mechanically alloyed-activated Ti-Si and TiH2 powders
Abstract
<p>Metallic implants are widely used in applications associated with bone. A major drawback of using metals is their elastic modulus which is higher than that of bone resulting in stress shielding and premature failure of the implant. The employment of biomaterials with a porous structure has the potential to lower the modulus and promote osseointegration. The present work investigates the microstructure formation and the resulting elastic modulus of a new Ti-Si-Zr alloy. The sintering procedure involves the use of both mechanically alloyed Ti-Si powder and TiH<sub>2</sub> to activate sintering with the TiH<sub>2</sub> also serving as a pore precursor. The procedure is designed to promote bonding but not consolidation. The influence of sintering temperature, heating rate, as well as the amount and size of the TiH<sub>2</sub> on the phases formed and porosity was investigated. It was observed that the use of TiH<sub>2</sub> increased the degree of porosity whilst the size of TiH<sub>2</sub> particles could be used to control the pore size. The results showed that when using small TiH<sub>2</sub> particles, the elastic modulus was strongly dependent on the fraction of TiH<sub>2</sub>. When large TiH<sub>2</sub> particles were used, the porosity had no significant influence on the elastic modulus. The variation in behavior could be attributed to differences in microstructure. To control the bulk modulus it is essential to understand the differences in the microstructure formation mechanisms between these two cases.</p>
