Abstract Anisotropic behaviors of cold rolled and annealed ULC steels are evaluated by orientation imaging microscopy (OIM) and magnetic Barkhausen emission (MBE) techniques. The MBE voltage is found higher along RD than TD, indicating the presence of favorable magnetic easy axis along RD for both 50 and 80% cold rolled steels. The recovery occurred at low temperature (T 500 °C) annealing leads to an abrupt drop of ‘k’ value for both cold rolled steels. Furthermore, the kernel average misorientation map, obtained from OIM, decreases with increasing annealing temperatures.

退火处理对冷轧ULC钢磁织构的影响

摘要 通过定向成像显微镜 (OIM) 和磁巴克豪森发射 (MBE) 技术评估冷轧和退火 ULC 钢的各向异性行为。发现沿 RD 的 MBE 电压高于 TD，表明 50% 和 80% 冷轧钢沿 RD 都存在有利的易磁化轴。恢复发生在低温（T 500 °C）退火导致两种冷轧钢的“k”值突然下降。此外，从 OIM 获得的内核平均取向差图随着退火温度的升高而减小。
