We report the influence of hydrogenation on residual stresses in an oxygen-implanted Ti-6Al-4V alloy. Prior to hydrogenation, oxygen ions were implanted in Ti-6Al-4V samples at fluence 3×1017 ions/cm2 with energies of 50 keV at room temperature and 550°C and 100 keV and 150 keV at 550°C. Hydrogenation was carried out on all samples at 550°C for two hours. Residual stresses were analysed by X-ray diffraction using the sin2ψ method and components of in-plane principal stresses were determined. Our results show compressive stress relaxation in all samples implanted with 50, 100 and 150 keV at 550°C as compared to unimplanted sample. Subsequent to hydrogenation, a stress shift to tensile side is observed in all implanted samples at 550°C.
