取向硅钢的再结晶织构因晶粒粗大而难以用Ｘ射线衍射测量．根据板材表面金相蚀坑的几何特征，确定了晶粒在欧拉空间的取向｛ψ，θ，φ｝，并编制出了由蚀坑测量参数直接求算ＯＤＦ的软件程序．采用该程序快捷而准确地求算了具有粗大晶粒的取向硅钢的三次再结晶织构．实算结果表明这种方法合理、实用，弥补了Ｘ射线织构分析方法之不足．

The recrystallized texture of oriented silicon steel is difficult to measure by X-ray diffraction due to coarse grain size. According to the geometrical characteristics of the corrosion pits on the surface of the plate, the orientation of the grains in the Euler space {ψ, θ, φ} is determined, and the software program for directly calculating the ODF from the pits is developed. Using this program, the tertiary recrystallization texture of grain oriented silicon steel with coarse grains was calculated quickly and accurately. The calculation results show that this method is reasonable and practical to make up for the lack of X-ray texture analysis methods.
