Abstract Scope |
The annealing texture evolution of cold-rolled high entropy alloy is studied especially focusing on the contribution of annealing twins. The material was cold-rolled to 80% reduction in thickness, and then annealed at 700°C for time varying from 5 min to 1 hour. The annealed specimens were characterized with in-situ transmission Kikuchi diffraction (TKD) technique. The Brass-type texture was developed in 80% cold-rolled specimens. The Brass, S, Goss, and shear texture components decreased as the annealing time increased. Moreover, some new orientations such as the Cube texture component and (φ1=90°,ϕ=30°, φ2=45°) orientation were evolved. The (φ1=90°,ϕ=30°, φ2=45°) orientation was close to the orientation corresponding to the 2nd, 3rd and 4th generations of annealing twins of the Brass texture component while the Cube texture component was close to the orientation corresponding to the 5th generation of annealing twins of the S texture component. |
