英文摘要: Abstract(#br)The growth behavior of columnar grains in non-oriented electrical steels is studied via the plastic deformation of an initial columnar-grained solidification microstructure and annealing, based on changes in grain orientation and grain orientation spread (GOS) value. The proportion of high-strain grains increased with increasing plastic deformation. Moreover, slender {1 0 0}-textured columnar grains with low GOS values are obtained from the anisotropy of the strain energy induced by the temperature gradient. Besides, relatively coarse {1 0 0}- and {1 1 0}-textured columnar grains are obtained with a higher GOS value, resulting mainly from the migration of grain boundaries along the rolling plane induced by the anisotropy of the surface energy. The development of...
