摘　　要：利用钛合金阻燃性能测试装置,结合金相分析,研究了TC4和TC11两种合金的抗燃烧性能,分析了钛合金燃烧产物的显微组织特点。利用摩擦学理论,推导了试验顶紧力与材料屈服强度关系,并利用该关系式,解释了同一环境条件下,不同合金燃烧临界顶紧力不同的主要原因。根据研究结果,指出了发展抗燃烧钛合金的几个方向。The combustion resistance properties of TC4 and TC11 titanium alloys had been studied by means of titanium combustion testing equipment and metallographic examination. The microstructure character of the combustion products had been analyzed. A formula, with regard to the impact pressure and the yield strength of the materials, had been deduced according to the tribology theory. Consequently, the reason, why different alloys need different critical impact pressure to lead into steady combustion state with identical circumstance, had been explained by this formula. Several approaches of developing combustion resistance titanium alloys had been suggested according to the conclusion.
