Achieving high strength and ductility simultaneously in high-entropy alloys (HEAs) has always been a challenge, and recent studies indicate that duplex microstructure provides a strategy to solve this contradiction. We prepared Al0.25FeCoNiV HEA with L12/B2 fine-grain duplex microstructure and achieved a remarkable combination of the ultimate tensile strength (1530 MPa) and ductility (20%), which clearly outperforms other duplex HEAs. Owing to the formation of fine-grain microstructure and the hindrance of the B2 phase, high yield strength has been achieved. Furthermore, the excellent work-hardening ability of the L12 phase and the dispersion of the B2 phase ensured uniform deformation and high strength. GRAPHICAL ABSTRACT IMPACT STATEMENT Al0.25FeCoNiV HEAs exhibit a remarkable combination of ultimate tensile strength and ductility through L12/B2 fine-grain duplex microstructure, which clearly outperforms other duplex HEAs.

In the present work, we have extensively examined the alternative-band microstructure of a Ti-47Al-2Cr-2Nb alloy fabricated via direct laser deposition by means of high resolution transmission electron microscopy and selected area electron diffraction. The studied samples exhibit two types of long-periodic stacking ordered phase with 6H and 18R structures, which were never reported for those obtained by traditional approaches. Moreover, the ordered phases possess stacking sequences of ABCBACA and ABCABCBCABCACABCABA, being analogous to the periodically arranged stacking faults in α2 and γ phases, respectively. With the presence of these unusual structures, the as-deposited sample tends to have superior mechanical properties. Impact statement Unusual ordered phases with long periodic stacking structures, seldom reported in the TiAl alloys obtained by traditional approaches, were comprehensively characterized, and demonstrated to possess excellent mechanical properties.
