It refers to a titanium alloy with a room temperature strength greater than 1100MPa after heat treatment. It includes three types: martensitic α+β alloy, near-metastable β titanium alloy and metastable β titanium alloy after heat treatment strengthening. It mainly replaces the high-strength structural steel commonly used in aircraft structures. It can reduce the weight of structural parts by 30%~40%, which can effectively reduce energy consumption and increase the life of aircraft.
At present, various high-speed aircraft in the world, such as airplanes and rockets, widely use high-strength titanium alloys as structural materials, especially in the application of spacecraft structural parts. At present, high-strength titanium alloy has become one of the main directions of titanium alloy development and application.
Application Mainly aviation and aerospace
Due to its excellent comprehensive properties, high-strength titanium alloy has been more and more widely used in the aerospace industry, and with the further development of high-strength titanium alloy, its application has gradually expanded to civil fields such as marine engineering, automotive industry and daily life.
Specifically, high-strength titanium alloys are generally used in aircraft structural parts, such as landing gear, tail support frame, main rotor and control system components of helicopters, etc. At the same time, high-strength titanium alloys are also used in aviation engines, mainly for the production of engine cabin partitions, helicopter engine blades, etc. Even the manufacture of multi-stage rockets cannot be separated from the participation of high-strength titanium alloys. For example, high-strength titanium alloys participate in the manufacture of solid fuel and liquid propulsion rocket engines, high-pressure gas cylinders, etc. of multi-stage rockets.
Future Development Direction and Problems
In recent years, due to the broad development prospects of high-strength titanium alloys, researchers have done a lot of research on the theoretical basis of its composition design, strengthening and toughening mechanism, processing and forming methods, etc., which provides a good theoretical basis for the application of high-strength titanium alloys in high-tech industries such as aerospace and marine engineering. It can be foreseen that high-strength titanium alloys will definitely become the major direction of titanium alloy development in the future.
However, developing and designing new high-strength titanium alloys is a complex and difficult process. The biggest problem is the cost of high-strength titanium alloys, because the alloying elements of β-titanium alloys are mostly expensive refractory metals, such as Mo (molybdenum), Nb (niobium), V (vanadium), etc., and due to the high concentration and high density of these β-stabilizing elements, β-titanium alloys also have higher density than other titanium alloys. Therefore, how to further improve the specific strength of β-titanium alloys is also the focus of future high-strength titanium alloy research.
