CMSX-4(Ni-Co-Cr-Ta-W)

1. Introduce – Second generation single crystal superalloys – High strength alloy with improved heat resistance compared to the first generation single crystal superalloys – Re, Hf, Nb, V, etc. are added to the basic composition of the first generation single crystal superalloy * Single crystal superalloy Superalloy developed to minimize grain boundaries to increase creep resistance and temperature acceptance The addition of grain boundary strengthening elements such as C, B, Zr, and Hf suppresses grain boundary formation and allows heat treatment at higher temperatures to in...
