无取向电工钢的定量物理模型需要精确了解材料的化学和微观结构参数，其中晶体织构是最重要的参数之一。描述这些材料的结构-性能关系是困难的，因为所有的参数都对磁性能有影响。在本研究中，一组无取向电工钢试样进行了检查，其中化学和晶粒尺寸保持类似的样品，但纹理是不同的。引入了一个新的织构参数--磁性织构因子，它定义为沿沿着方向的体积分数与沿方向的体积分数之比<100><111>。结果表明，与常用的{100}晶面与{111}晶面体积分数之比织构因子相比，该织构因子更能反映磁性随晶体织构变化的趋势。
Quantitative physical models for non-oriented electrical steels require precise knowledge of chemical and microstructural parameters for the material, with crystallographic texture being one of the most important. Describing the structure–property relationships in these materials is made difficult in that all of the parameters have an effect on magnetic properties. In the present study, a set of non-oriented electrical steel specimens are examined, where chemistry and grain size are kept similar from sample to sample, but texture is varied. A new texture parameter calledMagnetic Texture Factoris introduced which is defined as the ratio of the volume fractions of <100> direction to <111> direction along magnetization vector. It was found that thisMagnetic Texture Factorwas a better parameter for identifying trends of magnetic properties with crystallographic texture than the often usedTexture Factor, which is described as the ratio of the volume fractions of {100} planes to {111} planes.
