In this study, the influence of SiC nanoparticles on deformation texture of steel-based
nanocomposite fabricated by accumulative roll bonding process was investigated. It was
found that there was a texture transition from the rolling texture to the shear texture for
both pure interstitial free steel and steel-based nanocomposite. However, the texture
transition occurred in different cycles for the pure steel (the third cycle) and steel-based
nanocomposite (the first cycle). It was realized that the fraction of low misorientation
angle grain boundaries was decreased and the fraction of high misorientation angle grain
boundaries was increased by the number of cycles. Also, recrystallization occurred in the
pure steel and steel-based nanocomposite samples after the third and first cycles,
respectively. In addition, the occurrence of recrystallization in steel-based nanocomposite
was sooner than that of pure steel. At the early stage of dynamic recrystallization in
processed steels, the {011}< 100>-oriented grains were evolved and the fraction of grains
with α-fiber and γ-fiber orientations was slightly decreased. The formation of the rolling
texture in the steel-based nanocomposite samples was different from the typical rolling
texture for the pure steel samples, due to the presence of the SiC nanoparticles in the
nanocomposite. The weak rolling texture was attributed to the high stored energy of
deformation, which was, in turn, due to low deformation temperature
