A novel approach to the rapid synthesis of high‐entropy carbide nanoparticles.

A novel strategy for the rapid synthesis of high‐entropy carbide particles is proposed that involves the transformation of multicomponent intermetallic intermediates to multicomponent carbides (high‐entropy carbide precursors). (Ti0.25V0.25Nb0.25Ta0.25)C nanoparticles with a uniform solute distribution were successfully synthesized in an Al matrix by heating Al‐Ti‐V‐Nb‐Ta‐C powder mixtures at 1500°C for 10 minutes. The multicomponent aluminide intermediates led to the rapid formation of multicomponent carbides during heating to 1100°C, which transformed into a high‐entropy solid solution during heating to 1500°C. We developed a new rapid approach for the synthesis of high‐entropy ceramic particles. [ABSTRACT FROM AUTHOR]
