Abstract

Texture improvement has long been a challenging problem for non-grain oriented (NGO) silicon steel. In this work, the microstructure and texture evolution in Fe-3 %Si steel which was cold rolled by 83 % and further annealed by slow heating of 20 °C/s and rapid heating of 150 °C/s through electrical current passing the specimen were studied by electron back-scattered diffraction (EBSD) and X-ray diffraction (XRD). It was found that rapid heating effectively promoted the favorable recrystallization texture of λ (〈001〉//ND), Goss ({110} 〈001〉) as well as α (〈110〉//RD), while hindered the unfavorable texture of γ (〈111〉//ND). Rapid heating affects the texture competition by making the components with lower stored strain energy get more opportunities for nucleation and grain growth in terms of the modified recovery and recrystallization kinetics. Electrical current rapid heating, featured with high efficiency and low energy consumption, can act as a perspective approach to manufacture high-performance non-grain oriented silicon steel.

电流快速加热下非晶粒取向硅钢的再结晶织构演变

织构改善一直是非晶粒取向硅钢研究的难题。采用电子背散射衍射（EBSD）和x射线衍射（XRD）研究了经83%冷轧、20°C/s慢速加热和150°C/s电流快速退火的fe - 3% Si钢的显微组织和织构演变。结果表明，快速加热能有效促进λ (< 001 > //ND)、Goss（{110} < 001 >）和α (< 110 > //RD)的再结晶织构，而抑制γ (< 111 > //ND)的再结晶织构。快速加热影响织构竞争，使储存应变能较低的组分在修正的恢复和再结晶动力学方面获得更多的成核和晶粒长大的机会。电流快速加热具有效率高、能耗低的特点，是制备高性能无晶粒取向硅钢的一个重要途径。

期刊介绍： Materials Characterization features original articles and state-of-the-art reviews on theoretical and practical aspects of the structure and behaviour of materials. The Journal focuses on all characterization techniques, including all forms of microscopy (light, electron, acoustic, etc.,) and analysis (especially microanalysis and surface analytical techniques). Developments in both this wide range of techniques and their application to the quantification of the microstructure of materials are essential facets of the Journal. The Journal provides the Materials Scientist/Engineer with up-to-date information on many types of materials with an underlying theme of explaining the behavior of materials using novel approaches. Materials covered by the journal include: Metals & Alloys Ceramics Nanomaterials Biomedical materials Optical materials Composites Natural Materials.
