Change of Rotated Cube Texture through Multi-processing in 3% Si-steels

概要

論文の詳細を見る
Rotated cube texture was obtained about 5% during the 1st heavy cold rolling 80% and the subsequent annealing increased it by 40% but thereafter both the 2nd light cold rolling 10% and the 2nd low temperature annealing at 700°C were not able to increase the rotated cube orientation. This result assures that a small amount of reduction grows hardly the rotated cube orientation and even subsequent annealing of such lightly cold rolled materials does not increase it properly either. The γ fiber of hard magnetizing orientation revealed a large volume fraction above 20% through the 1st cold rolling and subsequent annealing, but it decreased noticeably after the 2nd cold rolling and annealing, which also means that it does not change under such low cold reduction and low temperature annealing. The CSL boundaries of Σ3, Σ7, Σ9 and Σ15 appeared as the main Σ boundaries.
