钛合金在Ar与O2气氛中的燃烧行为

Burning Behavior of Titanium Alloys in Mixture of Ar and O_2

摘要:

以ＤＣＳＢ法点燃钛合金，研究钛合金在Ａｒ气与Ｏ２气氛中的燃烧行为，分析常规钛合金一旦着火应采用什么方法灭火。研究结果表明：钛可在富氧环境中燃烧；钛的燃烧可用Ａｒ气灭火；钛在富氧环境中燃烧的产物及燃烧产物与基体的界面均不致密，燃烧可持续进行。

Abstract:

The burning behavior of titanium alloys in a mixture of Ar and O 2, and a way of extinguishing the titanium fire have been studied. It was shown that titanium burns in an oxygen rich atmosphere, and that Ar gas can be used to extinguish the fire. Both the burning products and interface between the burning products and matrix are porous when titanium burns in an oxygen rich atmosphere.
