However, the exact correlation between MGAT and texture evolution is a long-standing enigma. In the current research, the presence of MGAT was confirmed by transmission Kikuchi diffraction (TKD) and high resolution electron backscattered diffraction (EBSD) in partially (700 degrees C/5 min) and fully (700 degrees C/1 h) recrystallized specimens of equiatomic CoCrFeMnNi high entropy alloy, respectively. Further, the twin clusters in the vicinity of the potential nucleation sites (Brass, Goss and S orientations) were investigated to gain insights on the contribution of MGAT on texture development. The newly developed (phi(1) = 90 degrees, Phi= 30 degrees, phi(2) = 45 degrees) orientation showed its roots originating from 2nd generation twin of the Brass orientation while Cube orientation was evolved from the 1st and 5th generation twins of the S orientation.
