It is shown that the addition of Ti and Al can evidently decrease the oxidation rates of alloy,and both Nb-15Ti-11Al and Nb-30Ti-15Al(β+δ) show superior oxidation resistance than Nb-35Ti-6Al(β) which may be attributed to the decreased solubility and diffusion of oxygen in δ phase.
研究表明,元素Ti和Al的加入能有效改善合金的抗氧化性能,合金中δ相的存在降低了氧的溶解度,同时抑制氧的扩散,因而两相合金Nb-15Ti-11Al和Nb-30Ti-15Al(β+δ相)抗氧化性能优于单相合金Nb-35Ti-6Al(β相)。
