Fast and High‐Throughput Synthesis of Medium‐ and High‐Entropy Alloys Using Radio Frequency Inductively Coupled Plasma

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.
