以Fe-3.18%Si的热轧无取向硅钢片为原料,采用1100℃淬火、室温下70%的应变量变形,进行了500℃×0.5 h退火处理,制备了纳米亚微米晶粒尺度的薄硅钢片,并用透射电镜对其结构进行分析,用X-射线衍射议和透射电镜对样品中的纳米亚未晶粒结构和织构进行了分析。结果表明,热轧无取向硅钢片经1100℃淬火获得了板条马氏体组织,再经室温大变形和各种退火温度和退火时间的再结晶退火之后,得到纳米晶粒结构,并形成了(110)晶面的织构。
The hot-rolled non-oriented silicon steel sheet with Fe-3.18% Si was used as raw material, and annealed at 1100 ℃ for 70% of the deformation at room temperature for 500 ℃ for 0.5 h to prepare nano-micron grain size thin The microstructure and texture of the nanoshells in the samples were analyzed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results show that the hot-rolled non-oriented silicon steel sheet obtained after quenched at 1100 ℃ lath martensite, and then by a large deformation at room temperature and annealing temperature and annealing time annealing crystallization time, to obtain the nano-crystal structure, and formed (110) crystal plane texture.
