| 中文摘要: |
| 采用取向分布函数(ODF)分析了无取向电工钢冷轧板施加不同张力时再结晶退火后组织织构的变化。结果表明,随着退火张力的增加,再结晶晶粒尺寸逐渐增大,当退火张力为4 MPa时,晶粒平均直径达最大值75 μm,且尺寸均匀,Goss织构和立方织构组分也增强,其铁损P1.5/50降低到4.34 W·kg-1,同时磁感B50升至1.684 T；当张力增加到6 MPa时,晶粒直径减小至40 μm,{110}〈001〉和{001}〈100〉织构组分减弱,γ线织构组分明显增强,磁性能恶化。 |
| 英文摘要: |
| The recrystallization texture of non-oriented electrical steel under different annealing stress was investigated by orien-tation distribution function analysis. The result showed that the size of the recrystallization grain increased with the increase of annealing tension. When annealing tension was 4 MPa, the average diameter of grain reached the maximum of 75 μm with even size,and Goss texture and cube texture component were enhanced,as P1.5/50 was reduced to 4.34 W·kg-1 and B50 increased to 1.684 T. When annealing tension increased to 6 MPa, the grain size would decrease to 40 μm,leading to the decrease of intensity of {110}〈001〉 and {001}〈100〉texture, the increase of density of {111} fiber and the visible deterioration of magnetic property. |
