| 摘 要： | 采用SEM、EBSD和XRD等分析手段研究了退火温度对含Ce新能源无取向电工钢组织及织构的影响。结果表明:800 ℃退火后,试验钢边部和中心部位均能观察到再结晶组织及亚晶组织,α线织构中的{112}<110>取向密度最高,γ线织构中的{111}<112>取向密度较弱,退火板存在少量η织构;830～920 ℃退火后,温度越高,再结晶越充分,α线织构取向密度下降,γ线织构取向密度增加,η织构基本消失;试验钢在950 ℃退火后发生了完全再结晶,平均晶粒尺寸为48.29 μm,γ线织构中的{111}<112>取向密度最高,为11.36。

| Abstract: | Effect of annealing temperature on microstructure and textures of Ce-bearing non-oriented electrical steel for new energy automobiles was studied by means of SEM,EBSD and XRD. The results show that recrystallized and sub-crystalline microstructure can be observed in both edge and center after annealing at 800 ℃,the intensity of { 112} < 110 > orientation in α texture is highest,but that of { 111} < 112 > orientation in γtexture is weaken. In addition,a small amount of η texture exists in the annealing sheet. After annealing at the range of 830-920 ℃,the higher annealing temperature,the more sufficient recrystallization is,the intensity of α texture decreases while γ texture increases,but η texture totally disappears. The complete recrystallization of tested steel annealed at 950 ℃ has occurred,at which state the average grain size is 48. 29 μm and the highest intensity of { 111} < 112 > orientation in γ texture can reach 11. 36. |
