      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.},
