The high-temperature oxidation behavior and mechanism in a powder metallurgy Ni-based superalloy featuring δ-Nb3Al addition

Incorporating strengthening phase with a higher thermal stability than traditional L 12 -ordered Ni 3 Al phase offers a promising avenue for developing the next-generation Ni-based superalloys. In this study, a powder metallurgy superalloy featuring addition of high-melting-point δ -Nb 3 Al was fabr...
