a Schematic of the ultrahigh-temperature, heat-concentrated platform for multi-elemental metal melt mixing towards the fabrication of MPEAs. Due to the higher electrical resistance of the heating zone, only this area of the carbon felt produces a high temperature under the application of a voltage due to Joule heating. Multi-elemental metal powders are loaded continuously into the heat-concentrated zone of which the temperature can be tuned to as high as 3000 K with a uniform temperature distribution. The metal powders are rapidly heated, melted on the order of milliseconds, and alloyed into uniform MPEAs. b Photograph of the ultrahigh-temperature, heat-concentrated platform for multi-elemental metal melt mixing.
