A review on the recent advances concerning the fatigue performance of titanium alloys for orthopedic applications

Abstract This article presents a review on recent advances in the fatigue behavior of Ti alloys, especially main commercial compositions for orthopedic applications. In case well?known Ti–6Al–4V alloy, major concern is related to effect surface modification necessary improve osseointegration. The introduction discontinuities due growth porous oxide layer, or roughness development, may severely affect performance depending level alteration. additive manufactured Ti–6Al–4V, response also influenced by inherent defects as?built parts. Regarding recently developed metastable ? information about properties still scarce and mainly second phase precipitates, which are introduced optimize mechanical properties. alloys complex, as their microstructure, should not be neglected when being improved applied medical devices.
