Evolution of Microstructure and Texture Orientation of A New Non-oriented Electrical Steel during Annealing
摘 要
通过金相分析和电子背散射衍射技术研究了一种新型含铜无取向电工钢在950 ℃退火不同时间(3~180 s)空冷后的组织和织构取向的演变。结果表明: 该钢在退火3 s时的主要织构为α和γ线织构, {100}〈110〉织构最强; 退火20 s时织构以〈111〉〈112〉、{111}〈110〉、{112}〈110〉、高斯织构和立方织构为主, 随着退火时间的延长, 高斯织构和立方织构强度呈减弱趋势; 合理控制保温时间有利于提高{100}、{110}面织构的占有率。
Abstract
Evolution of microstructure and texture oriented of a new non-oriented electrical steel during annealing at 950 ℃ for different times(3-180) s and air cooling was studied by metallography and electron back-scattering diffraction analysis.The results show that after annealing for 3 s most of the texture oriented along α-fibre and γ-fibre,the intensity of {100}〈110〉 was the strongest.{111}〈112〉,{111}〈110〉,{112}〈110〉,Gauss texture and cube texture were the main texture after annealing for 20 s,with the prolongation of annealing time the intensity of Gauss texture and cube texture decreased.The controlling of annealing time could contribute to the increase of {100} and {110} plane texture.
