dc.description.abstractThe nanostructured TiMgSr (at.% 70:10:20) was synthesized by ball milling process followed by cold compaction and microwave sintering. XRD results after 30 h milling showed crystallite size of ⁓41 nm with a lattice strain of 2.5% and evolution of solid solutions like Mg<inf>5</inf>.<inf>2</inf>Sr, MgTiO<inf>3</inf>. The phases formed from 30 h mechanically alloyed powder are in good agreement with TEM SADP results. Consolidation using microwave sintering resulted in the retention of nanostructure with crystallite size of 78 nm and lattice strain of 1.2%. Densification study results in porosity of 19.8% with almost 20% density reduction compared to CP-Ti. The obtained porosity has promoted density reduction along with low elastic modulus that could be biocompatible with human bone tissue. Nanoindentation test results showed a low modulus of 36 ± 7 GPa with a hardness of 1.8 ± 0.8 GPa. These results are comparable with those Ti alloys produced by various techniques and found to be relatively superior for biomedical applications. © 2022
