What is it about?
Up to now, most bcc HEAs studied in the literature contain one or more high-activation elements, such as Mo and Nb, and suffer from poor room temperature ductility. By contrast, the investigations of low-activation bcc HEAs, especially regarding mechanical behavior, are very lacking. Our analysis gives a “ductility rule” to narrow the search space for ductile bcc HEAs and implies the opposite natures of high-activation group and low-activation group, motivating us to further study the latter in the future.
