[225] Effect of alloy microstructure on oxidation resistance of alumina scale forming γ-γ’ two phase alloys

*Zhentao WANG1, Suzue Yoneda1, Shigenari Hayashi1 (1. Hokkaido Univ.)

Keywords:high temperature oxidation、Ni-based alloy、γ-γ' two phase、initial oxidation、oxidation kinetics

Ni-based high temperature alloys are often strengthened by γ’. When γ’ precipitates in the γ phase, Al content in matrix decreases, which might decrease the ability to form a protective scale.
