Abstract: Fe-Si ribbons and thin sheets with 6.5%Si content were prepared by means of the single roller rapid solidification and chemical vapor deposition (CVD), respectively. The initial textures of rapidly solidified Fe-6.5%Si ribbons were characteristic of the {100} fiber-type, which became weakened during primary recrystallization in various atmospheres. At the stage of secondary recrystallization, the {100} texture formed in Ar and the {110} texture in hydrogen, while there occurred a texture transformation from the{100} type to the{110} type in vacuum with the increase of annealing temperature. For Fe-6.5%Si sheets prepared by Si deposition in old-rolled Fe-3%Si matrix sheets, their textures were dominated by the h-fiber (<001>//RD) with the maximum density at he {120}<001> orientations. After homogenization annealing, the h-fiber could evolve into the {130}<001> type or become more concentrated on the {120}<001> orientations, depending on the cold rolling modes of Fe-3%Si matrix sheets.
