AI-generated Abstract
The paper explores the microstructural characteristics and high-temperature behavior of chromium-rich cobalt-based alloys containing hafnium carbides. Prioritizing the stability of carbide reinforcements at elevated temperatures, the investigation focuses on three alloys within the Co-Cr-Ce-Hf system, designed for improved oxidation resistance and mechanical properties. Results demonstrate the influence of chemical composition on microstructure and hardness after exposure to high temperatures, highlighting the potential of HfC as a more stable reinforcement compared to traditional chromium carbides.
