Resumo

The effect of hot band grain size on the texture of low silicon steels was investigated. In spite of different hot band grain sizes (22, 125 and 500 pm), the deformation texture is formed by the fibers < 111>//ND and < 111 >//RD. Nevertheless the recrystallization texture is strongly affected. Increasing the hot band grain size, from 22 to 125 mum, the intensity of the Goss component in the recrystallized material increases and { 111 } components decreases, The further increase to 500,mum does not increase Goss, but increases cube on face component. When the hot band grain size is sufficiently large (similar to500mum) the deformed grains tend to recrystallize independently, originating regions (clusters) of grains with same orientation. There is no apparent effect of an intermediate recovery (after deformation epsilon=0.7 annealing at 500degreesC during 1 h) on the deformation or recrystallization textures. (AU)
