“…Ternary and higher-order alloys, by contrast, remain relatively unexplored. The BW method has been used to study ordering in bcc ternary alloys [9,10,11,12] with special emphasis on the Heusler structure [13,14,15,16], and in fccbased alloys [17]. In these examples, 'canonical' EPIs were used to study general trends, or were inferred experimentally for more quantitative studies.…”
