双取向硅钢微结构对二次再结晶织构的影响

Effect of Microstructure on Secondary Recrystallization Texture of Dual-Oriented Silicon Steel

利用X射线衍射技术测定了双取向硅钢的微结构和织构,分析了形变储能与二次再结晶织构之间的关系,以探讨二次再结晶织构形成的机制。结果显示,在经受初次再结晶处理后的试样中仍残留有数量可观的形变储能,且在二次再结晶完成后的试样中,有利的织构组分——立方织构({100}<001>)的强度随残余储能的增加而增加,证实了形变储能在二次再结晶织构形成中的作用。

The microstructure and texture of dual-oriented silicon steel were measured by using X-ray diffraction. The relationship between deformation stored energy and secondary recrystallization texture was analyzed in order to clarify forming mechanism of secondary recrystallization texture. The test results showed that the stored energy was obviously remained in the primary recrystallization samples, and the intensity of beneficial cube texture { 100 } 〈001 increased with the increasing of residual stored energy, which indicated that the residual stored energy had positive role on improving secondary recrystallization texture.
