Structural and mechanical evaluation of the effect of oxygen boost diffusion on a gamma titanium aluminide of Ti–45Al–2Nb–2Mn–1B Air oxidation, vacuum heating and a subsequent oxidation (DT treatment) of Ti–45Al–2Nb–2Mn–1B (at.%) titanium aluminide resulted in several oxide layers and a hard Ti3Al as an interlayer between the substrate and the oxide layers. Surface characterization was […]
