| Abstract Scope |
High entropy alloys (HEAs) have attracted much attention due to their unique properties such as high strength, good wear and corrosion resistance, and outstanding low and high temperature performance. However, the recent studies mainly focused on the investigation of equiatomic HEAs. This current study focused on (Nb-Ni-Ti-Mo-V-Hf) microalloyed non-equiatomic Al-Co-Cr-Fe HEAs. The thermal and phase stability, microstructure and mechanical properties of as-cast and heat treated alloys were investigated using a combined characterization techniques of differential scanning calorimetry (DSC), X-ray diffraction (XRD), optical microscope (OM) and scanning electron microscope (SEM) and hardness tests. The effects of microalloying elements on the mechanical properties of non-equiatomic Al-Co-Cr-Fe based HEAs will be discussed |
