The combustion behavior and mechanism of Ti14 titanium alloy are studied by promoted ignition combustion tests at different oxygen pressures in this paper. The burning velocity increases at higher oxygen pressures and also increases with longer burning times instead of a constant at the same pressure. The Cu atoms are found enriched in two zones-i.e., the heat affected zone and melting zone during the combustion process-which can prevent the diffusion process of oxygen atoms. The different combustion behavior of Ti14 and Ti-Cr-V alloys is basically controlled by the characteristics of phase structures and chemical reactions.
本文通过在不同氧气压力下的促进点火燃烧试验研究了Ti14钛合金的燃烧行为和机理。在较高氧气压力下燃烧速度增加，并且在相同压力下随着燃烧时间延长也增加，而不是保持恒定。发现在燃烧过程中Cu原子富集在两个区域，即热影响区和熔化区，这可以阻止氧原子的扩散过程。Ti14合金与Ti-Cr-V合金不同的燃烧行为基本由相结构和化学反应的特性控制。
