      abstract     = {Enhancing the strength of metallic materials usually
                      compromises their ductility since bothproperties are
                      intrinsically decided by chemical bond strength but with
                      opposite dependencies.Despite great effort via
                      microstructural regulation, tackling the strength-ductility
                      paradox inmetals and alloys remains a challenge. To achieve
                      superior strength-ductility combination, herewe report an
                      integrated metastable and heterostructured alloy design
                      strategy. Guided by ab-initiothermodynamics and dynamics
                      calculations, a novel metastable Fe68Ni12Cr10V10 (at. $\%)$
                      dualphaseeutectic multicomponent alloy in which the
                      martensitic transformation may occur underdeformation was
                      fabricated. By applying routine thermomechanical processing,
                      a multiheterostructuredmaterial characterized by alternating
                      fcc and bcc lamellae, fully recrystallizedfcc grains and
                      unrecrystallized bcc grains, as well as a bimodal
                      distribution of fcc grains, wasobtained. Yield strength of
                      the material is comparable to that of the high-strength bcc
                      referencealloy, while its ductility also surpasses the
                      ductile fcc reference alloy. By in-situ high-energy
                      X-raydiffraction measurements, the superior
                      strength-ductility synergy was found to originate from
                      thecoupled effects of hetero-deformation induced
                      strengthening and transformation-induced
                      plasticity.Specifically, the high strength is primarily
                      ascribed to the strengthening imparted byalternating soft
                      fcc and hard bcc lamellar structures. The exceptional
                      ductility stems from multistageα'-martensite transformation
                      over a broad strain range, which is unique to the
                      multiheterostructure.The synergistic effects of the
                      heterostructure and the athermal transformationoffer a
                      practical route to endow advanced materials with superior
                      mechanical properties.},
