Abstract The oxidation resistance of titanium alloys is an important property for high-temperature applications. Here, the oxidation–nitridation-induced recrystallization at the oxide–metal interface of a near-α titanium alloy substrate was analyzed using electron-backscatter diffraction and scanning transmission electron microscopy after oxidation tests at 750 °C for 500 h in air. Oxidation–nitridation-induced recrystallization was promoted by the enrichment of nitrogen at the interface, and grains comprising Ti 2 N and Ti 3 AlN grew from the interface with the inhomogeneous distribution of nitrogen.

近α钛合金的氧化-氮化诱导再结晶

摘要 钛合金的抗氧化性是高温应用的重要性能。在这里，在 750°C 空气中氧化 500 小时后，使用电子背散射衍射和扫描透射电子显微镜分析了近 α 钛合金基材的氧化物-金属界面处的氧化-氮化诱导再结晶。界面处氮的富集促进了氧化-氮化诱导的再结晶，包含Ti 2 N和Ti 3 AlN的晶粒从界面处生长，氮分布不均匀。
