DOI: 10.1007/s10853-020-04870-6
Abstract: Despite having otherwise outstanding mechanical properties, the practical application of CrCoNi medium-entropy alloy (MEA) is limited by its insufficient room temperature yield strength. Unfortunately, most traditional approaches for increasing strength usually lead to the degradation… read more here.
