Texture formation in face-centered cubic high-entropy alloys

High-entropy alloys (HEAs) have attracted much attention both from academia and industry mainly because of their particular properties giving hope for future structural and functional applications. As texture leads to an anisotropy of the properties, it is the aim of this paper to present a detailed review on texture evolution in face-centered cubic (FCC) HEAs during thermo-mechanical processing. Key results from published articles provide an up-to-date information regarding texture formation in these HEAs during tension, compression, rolling and shear deformation. The characteristics of deformation texture is similar to that of other conventional low/medium stacking fault energy (SFE) alloys such as high manganese steels and Ni-60wt%Co alloys. However, the overall texture intensity is quite low even after heavy deformation. The recrystallization textures of FCC HEAs show a weak retention of brass-type deformation texture components and texture randomization. New orientations during recrystallization mostly have first order twin relationship with the deformation texture components. Most of the first order twin orientations are retained during grain growth indicating the absence of preferential growth of certain crystallographic orientations. Finally, similarities and differences in texture evolution to other conventional low/medium SFE alloys are discussed.
