摘要：

A direct comparison between the oxidation behavior of Ti-6Al-4V and Ti-6Al-4V + 1B has been conducted to elucidate whether the addition of boron to Ti-6AI-4V impacts the oxidation behavior. Industrially prepared sheet of Ti-6Al-4V and Ti-6Al-4V + 1B were oxidized at temperatures between 650 and 950 degrees C for holding times of 25 and 50 h. Weight-gain measurements and characterization of surface and near surface microstructures showed that the addition of 1 wt% B increased the material's oxidation resistance. Additionally, the ingress of oxygen tends to decrease the solubility of other alloying species in alpha-Ti and leads to the formation of a distinctive and atypical microstructure with a distinct morphology.
