Abstract

Ni₃Al-based superalloys are widely used in aero-engine parts. In addition to having a good temperature bearing capacity, the oxidation resistance of the alloy is also high. In this work, a multiphase Ni₃Al-based superalloy was selected as the experimental material. Three micro-regions (γ' + γ dendrite, interdendritic β phase, and γ' envelope) containing different phases were obtained by heat treatment. The isothermal oxidation behavior of the micro-regions was studied under 1000^oC, where the three micro-regions exhibited different oxidation behaviors at the initial stage of oxidation. The γ' envelope has an obvious double-layer oxide scale showing a cellular bulge. The outer layer is a mixed layer (NiO, NiFe₂O₄, and Al₂O₃), and the inner layer is a single Al₂O₃ layer. However, the γ' + γ dendrite and the interdendritic β phase form a single layer of the Al₂O₃ film. With increasing isothermal oxidation time, the oxide scale composition of the three micro-regions gradually tends to be the same, forming a dense single Al₂O₃ layer.

Key words: Ni₃Al-based superalloy oxidation behavior γ' phase β phase
