Abstract This paper examines the distribution of the tangential and normal components of the magnetic leakage fields in pole-magnetized sheet materials, such as cold-worked structural steels St3, 09G2S, and 08G2B, as well as electrical steel with different grain structure and coarse-grained magnetically soft alloy Alfer, which have different types of texture induced by rolling and uniaxial tension. It has been found that even minor changes in the preferential orientation of easy magnetization axes 〈100〉 strongly affect the distribution of the tangential Н τ and normal H n components of magnetic leakage fields. For all studied materials, the magnitude of Н τ significantly exceeds that of H n . However, in most cases, the component Н n exhibits a larger anisotropy than Н τ . Cold plastic working by rolling and uniaxial tension changes the texture state of the studied structural steels with the formation of multicomponent textures, which causes changes in the angular dependences of the parameters Н τ and H n . This fact indicates that the onset of plastic flow in a ferromagnetic material can be detected by changes in the form of circle diagrams of the leakage field components. The circle diagrams of the parameters Н τ and H n of deformed structural steels have the form of figure-eight patterns that are approximately perpendicular to each other. The position of the maxima of Н τ and H n on these diagrams corresponds to the position of the projections of the easy magnetization axes closest to the rolling plane, i.e., the directions along which iron and its alloys have the lowest strength. Therefore, it may be effective to estimate the anisotropy of strength properties of steel products with different texture states by the anisotropy of their magnetic parameters. More reliable results of magnetic texture analysis can be obtained by constructing full circle diagrams of the magnetic leakage field parameters.

结晶织构类型对钢板漏磁场参数各向异性的影响

摘要 本文研究了极磁化薄板材料，如冷加工结构钢 St3、09G2S 和 08G2B，以及不同晶粒结构和粗晶粒的电工钢中漏磁场的切向分量和法向分量的分布。粒状软磁合金 Alfer，具有由轧制和单轴拉伸引起的不同类型的织构。已经发现，即使易磁化轴 〈100〉的优先取向的微小变化也会强烈影响漏磁场的切向 Н τ 和法向 H n 分量的分布。对于所有研究的材料，Н τ 的大小显着超过 H n 的大小。然而，在大多数情况下，分量 Н n 表现出比 Н τ 更大的各向异性。通过轧制和单轴拉伸冷塑性加工改变了所研究结构钢的织构状态，形成了多组分织构，这导致参数 Н τ 和 H n 的角度依赖性发生变化。这一事实表明，可以通过泄漏场分量的圆图形式的变化来检测铁磁材料中塑性流动的开始。变形结构钢参数Н τ 和H n 的圆图呈相互近似垂直的八字形图案。这些图上Н τ 和H n 的最大值位置对应于最靠近轧制平面的易磁化轴的投影位置，即铁及其合金强度最低的方向。所以，通过磁参数的各向异性来估计不同织构状态钢材强度性能的各向异性可能是有效的。通过构建漏磁场参数的全圆图，可以获得更可靠的磁织构分析结果。
