abstract = {In this study, novel non-equiatomic CoCrFeMnNi-based
medium- and high-entropy alloys (M/HEAs) weredesigned to
activate distinct deformation mechanisms, including
twinning-induced plasticity (TWIP)
and/ortransformation-induced plasticity (TRIP). Tensile
tests were performed at 298 and 173 K. A variety of
ex-situmultiscale characterization techniques, strengthening
modeling, thermodynamic modeling (CALPHAD method),and ab
initio density functional theory (DFT) calculations were
employed to investigate the structural andmicrostructural
evolution, enabling accurate identification of the
strengthening and active deformation mechanismsoperating in
the M/HEAs. Strengthening modeling revealed that grain
boundary strengthening was theprimary contributor to yield
strength at both temperatures. A key finding of this study
is that a controlledFCC→HCP martensitic transformation,
associated with TRIP, enhances the strength-ductility
balance even whenthe resulting HCP phase reaches $~50\%$
volume fraction. This demonstrates that TRIP-enabled
metastabilityengineering is a promising strategy for
designing high-performance M/HEAs for next-generation
structural applicationsin energy, aerospace, and defense.},
