ABSTRACT
Titanium – Aluminum niobium oxide composite was fabricated by powder metallurgy technique. The effect of Nb2O5 ratio addition with (1, 1.5, 2, 2.5 wt %) ontheirmechanical, thermal, and microstructure were investigated. By introducing 2.5 % of Nb2O5 the hardness and compressive strength were increased approximately 20% and 46% respectively more than that of pure sample. while weight loss decreased to 4 2% at same ratio. Thermal Conductivity of composite in different temperatures (25, 50, 75 and 100 °C) was decreased 39, 43, 49, and 53 % respectively. Ti-6Al- 2.5 % Nb2O5 composite formed porous shape with niobium oxide. This kind of composite could be a promising candidate for implant material.
