| Abstract Scope |
Titanium alloys especially near α-Ti alloys are used for high temperature applications in jet engine components. The maximum temperature range that near α-Ti alloys can be used currently is up to 600℃. At temperatures above 600℃, its mechanical properties, in particular the strength decreases drastically due to the microstructure instability. If a new high temperature Ti alloy with improved properties to use in the temperature range 600- 700 ℃ has been identified, it would be possible to save weight and increase heat efficiency and thereby reducing the fuel cost.One of the effective techniques to enhance the mechanical properties is by alloying additions. In the present study, the effect of alloying additions like Zr and Co additions on near alpha Ti alloys on mechanical properties and microstructure features at room temperature and high temperature has been investigated.The results revealed that alloying additions significantly enhances high temperature properties. |
