- Abstract
- In this study, Al pack cementation was conducted on a high-entropy alloy (HEA), and the oxidation behavior of the pack-cemented HEA was investigated. The alloy was fabricated via powder metallurgy (PM). Al pack cementation was performed at 500 degrees C and 800 degrees C for up to 5 h. The microstructure was analyzed after the pack cementation process, and the phase identification was conducted. The oxidation test was conducted at 1000 degrees C for 3 h under air atmosphere, and the detailed microstructure was investigated using various analyses. The specimen that was pack-cemented at 800 degrees C for 5 h exhibited improved oxidation resistance, whereas the specimen that was not subjected to pack cementation and the one that was pack-cemented at 500 degrees C for 5 h demonstrated poor oxidation resistances. Microstructure and phase analyses were used to examine the diffusion of atoms and determine the oxidation behavior with regard to atomic diffusion.
