چکیده

In this study, the effect of SiC microparticles and nanoparticles on deformation texture of steel-based composite and nanocomposite fabricated by the accumulative roll bonding (ARB) process was investigated. Textural evolution during the ARB process was evaluated using X-ray diffraction. It was found that the presence of microparticles and nanoparticles in the IF steel matrix changed the intensity of texture components and fibers. There was a texture transition from rolling texture to shear one for pure IF steel, steel-based composite, and steel-based nanocomposite. However, the texture transition occurred in different cycles for these samples. It was realized that recrystallization occurred in pure IF steel, steel-based composite, and steel-based nanocomposite after the third, second, and first ARB cycles, respectively. In addition, occurrence of recrystallization in the steel-based composite and nanocomposite was sooner than in pure IF steel. Finally, it was found that with increasing the number of cycles, the fraction of low misorientation angle grain boundaries decreased and the fraction of high misorientation angle grain boundaries increased.
