Popis:	The texture evolution of modified 12%Cr steel in high-temperature compression was investigated under a 10, 25, 35, and 50% reduction at 1150°C by using Gleeble-1500 D thermal simulation machine. Electron backscattering diffraction analysis showed that the texture of modified 12%Cr steel varied within α, γ, and e and Goss fibers coexisting to γ and e , then to α and e , with the {hkl} orientation always existing in compression. Recrystallization nuclei contribute to γ-fiber strengthening due to their high-energy mechanism. First activated. α-fibers can be consolidated owing to the interaction of deformation and recrystallization. In the compression procedure of an ultrasupercritical high-pressure rotor made of modified 12%Cr steel, the deformation should be controlled under the recrystallization activation energy of α-fibers to obtain the microstructure featured by the γ-fiber recrystallization texture, and vice versa.
