| Abstract Scope |
High-entropy alloys (HEAs) are single-phase metallic materials made of multiple elements in nearly equal ratios, noted for their stability at high temperatures. The chemical synthesis of HEA nanoparticles (HEA-NPs) retains the benefits of bulk HEAs and offers higher surface energy. A new Fast Moving Bed Pyrolysis (FMBP) method creates contaminant-free, highly dispersed HEA-NPs. This research focused on the sintering processing of HEA-NPs based on Mo, Nb, Ta, Ti, Zr, and Ru synthesized by FMBP. Transmission Electron Microscopy (in-situ and ex-situ), electron diffraction, EDS, and X-Ray Diffraction were used to characterize the synthesized HEA-NPs and study their sintering. These results demonstrate the effectiveness of FMBP in producing HEA-NPs, opening new avenues for their use in advanced materials applications. |
