| Description | Journal: Iop Conference Series: Materials Science and Engineering The non-equiatomic $Al_{7.5}Co_{21.75}Cr_{5.5}Fe_{21.75}Mn_{21.75}Ni_{21.75}$ high entropy alloy was studied. After cold rolling and annealing at 700-900 °C, a dual-phase ultrafine-grained structure composed of the partially recrystallized fcc matrix and B2 particles was produced; complete recrystallization of the fcc phase was observed after annealing at 1000 °C. The B2 precipitates formation provided a significant strengthening of the alloy in comparison with the single-phase state. The alloy demonstrated an attractive combination of mechanical properties, presenting yield and ultimate tensile strengths of 900 MPa and 1200 MPa, respectively, along with a ductility of 22%. |
