Effects of Sn content on the microstructure, mechanical properties and biocompatibility of Ti-Nb-Sn/hydroxyapatite biocomposites synthesized by powder metallurgy

► The β-Ti type Ti-35Nb-xSn/15HA composites are obtained by HEMM and sintering. ► The Ultra fine grain sized Ti-35Nb-2.5Sn/15HA sintered composites are fabricated. ► The sintered composites have high compression strength and low elastic modulus. ► The sintered composites have high corrosion resistance. ► MC-3T3 osteoblast-like cells grew on the surface and showed good spreading.
