Conventional titanium alloys have a tendency to burn alkanes under certain conditions, which greatly limits their application. In response to this situation, countries have launched research on flame retardant titanium alloys and made some breakthroughs. Alloy c (also known as T with a nominal composition of 50Ti-35v-15Cr (mass fraction)) developed by Qiang Guo is a flame-retardant titanium alloy that is insensitive to continuous combustion and has been used in F119 engines. BTT-1 and BTT -3 is a flame-retardant titanium alloy developed in Russia, all of which are Ti-Cu-Al series alloys, which have very good thermal deformation process performance, and can be used to make complex parts.
