Homogeneity of microstructure and texture was investigated in the FCC phase of an (FCC + B2) AlCrFe2Ni2 high entropy alloy (HEA) after heavy warm-rolling and annealing. For this purpose, the HEA was 90% warm-rolled at 400 °C (A90) and 750 °C (B90) and annealed at varying temperatures. Both A90 and B90 specimens showed a much finer ultrafine microstructure and reduced FCC fraction at the mid-thickness than on the surface. While the A90 specimen showed the presence of typical rolling texture components, the B90 specimen showed a stronger CND component ({100} 〈110〉) on the surface and typical rolling texture components at the mid-thickness. This remarkable through-thickness inhomogeneity could be attributed to increased surface shear owing to a change in friction and adhesion behavior with increasing warm-rolling temperature. Annealing resulted in progressive transformation to a microduplex structure with a consistent increase in the FCC fraction. However, the mid-thickness region showed a greater FCC fraction than the surface due to faster transformation and finer microstructures. The annealed A90 specimens showed uniform through-thickness microtexture retained from the deformation texture. In stark contrast, the annealed B90 specimens showed considerable microtexture inhomogeneity originating from the retention of the CND component on the surface and typical deformation components at the mid-thickness. Overall, the microstructure and texture homogeneities show considerable dependence on the warm-rolling temperature, which should be important considerations for processing HEAs. © 2023 Elsevier Inc.
