“…Until now, more than three hundred reported HEAs have been designed based on more than thirty elements [5]. In order to increase the specific strength and further explore the soft magnetic properties of HEAs, elements like B, Si, P, and/or C with relatively small atomic weights are introduced into FeCoNi medium entropy alloys [28,29,30,31]. Surprisingly, some of these types of HEAs are able to easily form metallic glasses [28,29,30,31].…”
