对Ti-6Al-4V和Ti-6Al-4V + 1B的氧化行为进行了直接比较，以阐明向Ti-6Al-4V中添加硼是否影响氧化行为。将工业制备的Ti-6Al-4V和Ti-6Al-4V + 1B板材在650至950 ℃的温度下氧化，保持时间为25和50 h。增重测量和表征的表面和近表面的微观结构表明，添加1重量%的B增加了材料的抗氧化性。此外，氧的进入倾向于降低其他合金物质在α-Ti中的溶解度，并导致形成具有独特形态的独特且非典型的微观结构。(C)2016年6月，作者。爱思唯尔有限公司出版
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.
