针对新能源汽车的发展，制备了含Ni固溶强化、含Cu析出强化以及含Ni+Cu复合强化3%Si无取向硅钢，研究了强化方式对无取向硅钢组织、织构和性能的影响。结果表明：固溶强化型无取向硅钢热轧板中形成了粗大{221}<221>晶粒，冷轧过程中剪切变形明显并在退火后形成良好再结晶织构。析出强化型无取向硅钢热轧板中心层形成γ取向粗大晶粒，在后续的加工中γ织构逐渐增强并最终得到相对细小的再结晶晶粒。复合强化型无取向硅钢热轧板中保留了强λ取向带状组织，退火后形成了有益的Goss织构和λ织构。固溶强化型与复合强化型无取向硅钢磁感应强度B₅₀分别达到1.742、1.688 T,高于析出强化型无取向硅钢的1.645 T。同时，复合强化型无取向硅钢高频铁损最低，其P_1.0/400和P_{1.0/1 000}分别低至20.97、82.69 W/kg,这与其较小的晶粒尺寸和织构改善有关。强度计算结果表明：Ni元素固溶强化对强度的提高有限，屈服强度为468 MPa,纳米Cu析出可显著提高屈服强度（强度增量约200 MPa）,且主要来自于模量强... For the development of new energy vehicles, 3%Si non-oriented silicon steel were processed by solid solution strengthening with Ni, precipitation strengthening with Cu, and composite strengthening with Ni and Cu.
