Abstract To promote the manufacture of grain-oriented pure iron, the texture and inhibitor features of two samples A and B produced by different cold-rolling processes were studied by optical microscopy, X-ray diffraction, and transmission electron microscopy. The results showed that a higher content of inhibitor elements directly resulted in a greater number of fine inhibitors, which exhibited strong inhibitory ability, leading to more fine precipitates of appropriate size effectively inhibiting the growth of primary grains in decarburized bands (sheets) during the single-stage cold-rolling process. The formation of the component with {110}\001[ Goss orientation was greatly suppressed in the stage of primary recrystallization, and this component could hardly be observed in the decarburized band; by contrast, the {411}\148[-oriented grains grew. During the process of high-temperature annealing, abnormal growth occurred and secondary recrystallized grains (Goss orientation) merged with other matrix grains such as {111}\112[and {411}\148[. The magnetic induction of samples A and B at 800 A/m was 1.939 T and 1.996 T, respectively.
