Abstract The distribution of second phase particles with carbide as main particles in conventional grain–oriented electrical steels during cold deformation processes was observed by field emission scanning electron microscopy, while the areal density of particles of different sizes were statistically determinedThe results show that cold deformation lead in the crushing and dissolving of carbide particles. The dissolution of carbides particles is a spontaneous process when the size of particles are too small. The increase of small size carbide particles and dissolving during cold rolling process is helpful for secondary recrystallization and the forming of sharp Goss texture, it can also accelerate decarburizing procedure after first–time cold roll and advance the development of producing grain–oriented electrical steels with low temperature hot rolling method.
