摘要：The thermal oxidation behaviour of Ti-6Al-4V alloy as well as pure titanium under external bending strains was investigated through experimental and modelling approaches. Dislocation accumulation due to creep deformation was responsible for the acceleration of oxidation at initial stage. However, the promoted formation of alumina would retard the subsequent scale growth. Moreover, the bending strain had a multi-fold influence on the formation of oxygen diffusion zone. An analytical model was developed to predict the variation of growth stress within the oxide layer along with time. The prediction results agreed well with experimental data.
