Of uniform standards and methods of evaluation of aerospace titanium castings retardant properties

Of uniform standards and methods of evaluation of titanium flame retardant properties. Properly evaluate flame retardant properties of titanium alloys is one of the key technologies of flame Titanium precision castings  titanium alloys, including combustion simulation methods and testing techniques. Currently, the evaluation method on the flame retardancy is no uniform standard, countries have adopted different methods of testing. So retardant performance evaluation method to develop a unified standard titanium will effectively promote the exchange of national retardant titanium. (2) improve the overall mechanical properties of Titanium precision castings retardant. Compared with flame titanium, titanium alloy retardant poor mechanical properties, the working temperature is lower. On how to further improve the mechanical properties of the(3) reduce the flame titanium costs. Resistant Titanium alloy sheets contains a lot of noble metal elements V, resulting in higher costs, limiting its applications. Domestic scholars have adopted partial substitution of lower-priced Mo V for a certain amount of research to try. alloy of the need for a deeper study.
