Why is Stainless Steel Corrosion Resistant? Journal of Materials Science & Technology, https://doi.org/10.1016/j.jmst.2022.11.029. In this study, we developed a series of dual-phase Al(182x)Co30Cr(11+x)Fe(11+x)Ni30 (x= -1, 0, 1) eutectic and near-eutectic HEAs containing face-centered cubic (FCC) and body-centered cubic (BCC) phases. By combining experiments and theoretical models, we demonstrated that the synergistic increase in both strength and toughness in our fully eutectic HEA was derived from the high hetero-deformation-induced (HDI) strengthening/toughening associated with a high misorientation angle at the grain/phase boundaries.
