It is possible to develop a new type of titanium alloy tube that is applied at a higher lower working temperature. Compared with the developed high-strength low-temperature titanium alloy tube, it will have greater potential for saving metals and improving efficiency. The goal in the future is to develop a titanium alloy tube that can reach a temperature of 650 ° C. This alloy can be used on high-pressure turbine wheels, which can reduce the weight by 20% compared with the commonly used base wheels.
However, as the operating temperature increases, it will inevitably bring more new problems, such as surface oxidation, long-term mass metallurgical production stability, frictional corrosion, fire hazard and hot salt stress corrosion. Certain problems can be solved by surface coating or surface treatment, for which research is currently being actively carried out.
