| 摘 要： | 采用光学显微镜(OM)、电子背散射衍射(EBSD)等研究了铌对取向硅钢冷轧过程中的组织与织构的影响。结果表明:含铌正火板和不含铌正火板经冷轧后都是条带状组织,但含铌冷轧板在宽度方向更窄。铌元素的存在对织构也具有优化作用,经过中间退火后,含铌冷轧板二次冷轧织构得到明显改善,相较于不含铌二次冷轧板拥有强度较低的旋转立方织构以及强度较高的{111}<112>织构,其取向密度最高可达12.460。

| Abstract: | Effect of Nb on microstructure and texture of grain-oriented silicon steel during cold rolling was studied by means of OM and EBSD. The results show that both the Nb containing and the niobium free normalized plate have strip microstructure after cold rolling, but the Nb containing cold rolled plate is narrower in its width direction. The existence of Nb has an optimum effect on texture. After intermediate annealing, the secondary cold rolled texture of Nb containing cold rolled plate is obviously improved, compared with the second cold rolled plate without Nb, which has a lower strength rotating cubic texture and higher strength {111}<112> texture, with a maximum orientation density of 12.460. |
