Notes:
Various types of titanium alloys with high strength and low elastic modulus and, at thesame time, vanadium and aluminium free have been developed as surgical biomaterials in recentyears. Moreover, porous metals are promising hard tissue implants in orthopaedic and dentistry,where they mimic the porous structure and the low elastic modulus of natural bone. In the presentstudy, new biocompatible Ti-based alloy foams with approximate relative densities of 0.4, in whichSn and Nb were added as alloying metals, were synthesised through powder metallurgy method.The new alloys were prepared by mechanical alloying and subsequently sintered at hightemperature using a vacuum furnace. The characteristics and the processability of the ball milledpowders and the new porous titanium-based alloys were characterised by X-ray diffraction, opticalmicroscopy and scanning electron microscopy .The mechanical properties of the new titaniumalloys were examined by Vickers microhardness measurements and compression testing
