The chemical composition of XH60BT
Tech Center 2022-06-14 25
XH60BT(GH3044) alloy is a solid solution strengthened nickel-based superalloy (rich in W and Cr elements). It can maintain high strength, plasticity and good oxidation resistance below 900 ℃ and is widely used in aerospace. It can be used to make high-temperature components (such as gas generators, etc.). The microstructure of this alloy after solution treatment is single-phase austenite + carbides (including Cr M23C6 phase and W M6C phase rich), and usually also contains a small amount of TiN and TiC phases. Adding a small amount of C forms carbides between grains, thereby preventing grain coarsening and crack initiation, and playing a role in strengthening grain boundaries and enhancing fracture strength.
