Abstract

Abstract

Multiple principal element alloys (MPEAs), also known as high-entropy alloys, have attracted significant attention because of their exceptional mechanical and thermal properties. A critical factor influencing these properties is suggested to be the presence of chemical short-range order (SRO), characterized by specific atomic arrangements occurring more frequently than in a random distribution. Despite extensive efforts to elucidate SRO, particularly in face-centered cubic (fcc) 3d transition metal-based MPEAs, several key aspects remain under debate: the conditions under which SRO forms, the reliability of characterization methods for detecting SRO, and its quantitative impact on mechanical performance. This review summarizes the challenges and unresolved issues in this emerging field, drawing comparisons with well-established research on SRO in binary alloys over the past few decades. Through this cross-system comparison, we aim to provide new insights into SRO from a comprehensive perspective.
