Abstract

Abstract : Multiprincipal element alloys, or medium‐ and high‐entropy alloys (MEAs and HEAs), hold great potential for numerous structural and functional applications, yet the synthesis of such alloys out of a vast composition space is a daunting task. Herein, a radio frequency inductively coupled plasma (RF‐ICP) method for preparing bulk MEAs and HEAs in a rapid and high‐throughput fashion is reported. Typical MEAs and HEAs are successfully synthesized within 40 s per alloy, thereby greatly improving the fabrication efficiency and throughput. This method provides a new opportunity to accelerate the discovery of new complex alloys for a broad range of applications.
