High-entropy Mn-based damping alloys, such as MnCuNiFeZnAl with a mixing entropy of 9.39 Jmol−1K−1, are promising for high-temperature use. In-situ XRD shows oxidation starts at 673 K, forming MnO, ZnO, and CuO, followed by Mn3O4 and Mn2O3. The alloy demonstrates enhanced antioxidation performance due to a continuous Al2O3 film near the oxidation film/matrix interface but is prone to oxide scale detachment at high temperatures. Splitting of MnO diffraction peaks arises from Mn2O3/Mn3O4 redox reactions or replacement of MeO (Zn, Cu, Ni, Fe) by Mn.
