- Title
High-Entropy Alloys: A Current Evaluation of Founding Ideas and Core Effects and Exploring 'Nonlinear Alloys'.
- Authors
Miracle, Daniel
- Abstract
The burgeoning field of high-entropy alloys (HEAs) is underpinned by two foundational concepts, and early research has been motivated by several hypotheses known as 'core effects.' The field is now entering its teenage years, and sufficient data have been collected to evaluate these hypotheses and to take a fresh look at the foundational concepts. Although recent assessments have concluded that two of the four HEA hypotheses are not supported by available data, new studies are already coming online to extend these analyses, and new interpretations are inspiring new directions for research within the field. This article gives an up-to-date evaluation of the HEA 'core effects' and proposes 'nonlinear alloys' as a new strategy to embrace the founding concept of compositional and microstructural vastness.
