Titanium alloys are favored in the aerospace industry due to their high specific strength

high specific stiffness

and high temperature resistance. Only through alloying method

titanium alloys cannot meet the demand of aerospace equipment with service temperatures higher than 600 ℃

such as ultra-high-speed aircraft and new aero-engines. To achieve better high-temperature performance

one of the effective ways is to tailor in-situ synthesized hybrid reinforcements into hightemperature titanium alloys. The resulting new composites

also known as heat-resistant titanium matrix composites (HRTMCs)

have received widespread attention because of their increased service temperatures of 50 – 200 ℃ compared to traditional titanium alloys. Regarding the development of HRTMCs

the corresponding research progress and application status were reviewed in terms of design and preparation of microstructural architectures

near-net-shape processing technology (including additive manufacturing

precision casting

isothermal superplastic forming) and high-temperature mechanical properties. Finally

the remained problems and future research directions of the HRTMCs were also pointed out.
