| description | In small volume fractions, the bcc phase plays an important role in the properties of FeCoNiCrMnAl<sub>0.5</sub> multiple-phase high-entropy alloys (HEAs). Since the small volume fraction of the bcc phase limits the detection of its texture, its texture evolution during mechanical processing is still unclear. In the current research, high-energy X-ray diffraction was used to investigate the crystallographic textures of cold-rolled and annealed FeCoNiCrMnAl<sub>0.5</sub> dual-phase HEA with fcc and bcc phases. During cold-rolling deformation, multi-pass symmetry under isothermal conditions leads to asymmetric {200}<sub>bcc</sub> and {211}<sub>bcc</sub> peaks; the asymmetry disappears after annealing treatment, with the evolution of prominent texture components and the release of internal residual stress. The Goss texture component and {112}<110> and {111}<112> texture components were intensified after cold-rolling in the fcc and bcc phases, respectively, with orientation relationships of {110}<sub>bcc</sub><111><sub>bcc</sub>//{111}<sub>fcc</sub><110><sub>fcc</sub> recognized in the cold-rolled HEA. Based on this relationship, the yield strength (YS) and engineering ultimate tensile strength (UTS) of the sample reached 570 MPa and 920 MPa, respectively, which shows a fracture elongation of 27%. The study provides deeper insight into the anisotropic mechanical characteristics of the investigated HEA and demonstrates the great potential of dual-phase HEAs for mechanical applications in industry. |
