观察了取向硅钢极薄带经冷轧至不同厚度,并经过不同工艺热处理后的显微组织及亚结构。结果表明:冷轧压下量越大,显微组织中位错密度越高,冷变形组织越多,等轴晶粒越少;增加冷轧压下量可以使试样的再结晶温度降低,当钢带厚度为0.08 mm时,在650℃退火时就能发生明显的再结晶。 Microstructure and substructure of the grain oriented ultra-thin silicon steel sheets is analyzed,which are rolled down to different thickness and treated with different heat treatment process.The result shows that there are higher dislocation density,more cold deformation structure and less equiaxed crystal grain in microstructure of the steel sheets with more cold rolled reduction.Increase of cold rolled reduction will decrease recrystallization temperature,and when thickness of the steel shee...
