中文摘要

In this study, the effect of decarburization annealing temperature and time on the carbon content, microstructure, and texture of grain-oriented pure iron was investigated by optical microscopy and scanning electron microscopy with electron-backscatter diffraction. The results showed that the efficiency of decarburization dramatically increased with increasing decarburization temperature. However, when the annealing temperature was increased to 825℃ and 850℃, the steel's carbon content remained essentially unchanged at 0.002%. With increasing decarburization time, the steel's carbon content generally decreased. When both the decarburization temperature and time were increased further, the average grain size dramatically increased and the number of fine grains decreased; meanwhile, some relatively larger grains developed. The main texture types of the decarburized sheets were approximately the same:{001}<110> and {112~115}<110>, with a γ-fiber texture. Furthermore, little change was observed in the texture. Compared with the experimental sheets, the texture of the cold-rolled sheet was very scattered. The best average magnetic induction (B₈₀₀) among the final products was 1.946 T.

Abstract

In this study, the effect of decarburization annealing temperature and time on the carbon content, microstructure, and texture of grain-oriented pure iron was investigated by optical microscopy and scanning electron microscopy with electron-backscatter diffraction. The results showed that the efficiency of decarburization dramatically increased with increasing decarburization temperature. However, when the annealing temperature was increased to 825℃ and 850℃, the steel's carbon content remained essentially unchanged at 0.002%. With increasing decarburization time, the steel's carbon content generally decreased. When both the decarburization temperature and time were increased further, the average grain size dramatically increased and the number of fine grains decreased; meanwhile, some relatively larger grains developed. The main texture types of the decarburized sheets were approximately the same:{001}<110> and {112~115}<110>, with a γ-fiber texture. Furthermore, little change was observed in the texture. Compared with the experimental sheets, the texture of the cold-rolled sheet was very scattered. The best average magnetic induction (B₈₀₀) among the final products was 1.946 T.
