The tensile properties of titanium processed by surface mechanical attrition treatment

In this work, the tensile properties of nanocrystalline Ti and bulk Ti processed by surface mechanical attrition treatment (SMAT) have been studied. The natiocrystalline Ti shows high strength which can be comparable to that of Ti-6Al-4V together with depressed plasticity. On the contrary, the strength of bulk Ti after SMAT is obviously improved with acceptable ductility and this new material has a potential biomedical application. (C) 2008 Elsevier B.V.
