Abstract The variation in plastic deformation of Fe-6.5 wt%Si alloy depends on antiphase domains and grain boundary character distribution. With the increase of rolling reductions from 50% to 85%, the increment of dislocation density causes decline of the sizes of antiphase domains, meanwhile the sharp and homogeneous distribution of γ-fiber texture is prone to obtaining a large fraction of CSL boundaries, thus the fracture deflection of 65% warm-rolled sheet is increased to 8.6 mm by 38.7% in comparison to that of 50% warm-rolled sheet (6.2 mm), and that of 85% warm-rolled sheet has nearly three times increment (18.2 mm).

压下量对Fe-6.5 wt%Si合金反相畴、晶界特征分布及塑性变形的影响

摘要 Fe-6.5 wt%Si合金塑性变形的变化取决于反相畴和晶界特征分布。随着轧制压下率从 50% 增加到 85%，位错密度的增加导致反相畴尺寸减小，同时γ-纤维织构的尖锐均匀分布容易获得大比例的 CSL 边界，因此65%温轧板断裂挠度比50%温轧板（6.2mm）增加38.7%，85%温轧板断裂挠度增加近3倍（18.2mm）毫米）。
