| Abstract Scope |
High-entropy alloys (HEAs) are promising materials for high-temperature structural applications due to their outstanding mechanical and thermal stability. In this study, mechanically alloyed CoCrFeNiAl₀.₆ HEA was reinforced with 2–4 vol.% B₄C and consolidated via spark plasma sintering (SPS) at 1000 °C under 40 MPa for 5 minutes. The aim of this study is to investigate the effects of B₄C addition on the microstructural and mechanical properties of the alloy. The unreinforced CoCrFeNiAl₀.₆ structure exhibited both FCC and BCC phases, with a measured density of 7.38 g/cm³ and a hardness of 4.3 GPa. Wear tests at room temperature and 600 °C, as well as high-temperature oxidation tests, will be performed. The influence of B₄C content and testing temperature on phase formation, microstructure, and mechanical behavior will also be evaluated. The findings are expected to support the development of ceramic-reinforced HEA systems for high-temperature engineering applications. |
