Fireproof property is a key performance index to measure the safety of aero-engine titanium fire

which is generally evaluated by the abilities of titanium alloy materials/components to resist thermal spontaneous combustion

ignition and extended combustion. Aiming at the demand of advanced high-temperature titanium alloys for highperformance aero-engines

this paper reviews recent experimental studies on ignition resistance and combustion resistance and introduces the research progress of non-isothermal oxidation behavior and fireproof mechanism of fireproof titanium alloys

high temperature titanium alloys and intermetallic titanium aluminides from the aspect of thermal spontaneous combustion resistance. Finally

the future direction of development is prospected.
