Development needs of high-performance titanium wire price

Aviation Research and Application of Titanium Alloys

Development needs of high-performance titanium wires‍ aircraft engines pulling the development of high-temperature titanium alloy, titanium alloy using the temperature gradually increased from the 1950s to the alloy represented through improved to alloy represented. Currently, representatives of the international advanced high temperature titanium alloy United States, Britain, Russia and China. Composition and performance characteristics of high temperature titanium alloy. Problems flame titanium research and development direction present, except the United States and Russia, some typical titanium retardant has been applied, the study of other countries on the flame is still in the research phase titanium alloy, titanium alloy type flame retardant less costly and flame retardant properties of non-uniform evaluation methods have hindered the development of fire-retardant titanium. Through research, the authors believe that the development direction of the flame titanium alloy mainly: (1) development of uniform standards and methods of evaluation of titanium flame retardant properties. Properly evaluate flame retardant properties of titanium wire‍ titanium alloys is one of the key technologies of flame titanium, 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 alloys 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 alloy of the need for a deeper study. (3) reduce the flame titanium costs. Resistant titanium alloy contains a lot of noble metal elements V, resulting in higher costs, limiting its applications. Domestic scholars have adopted partial substitution of lower-priced titanium whole distributor‍ Mo V for a certain amount of research to try.
