依取向空间的等体积划分原理,将传统的六方晶系材料特征非对称子空间(等角法)予以改造。并按等面积投影法对 ODF 图进行重建。按此法对实测的冷轧 TA7 合金板材完整ODF 施行织构分析。结果表明,织构分析与原等角法的完全等效;此方法能清晰地建立起反极图与 ODF 图之间的关系。等面积投影法的采用使织构定量简便、易行。
According to the equal volume partitioning principle of orientation space, the traditional hexagonal system material characteristic asymmetric subspace (isometric method) is modified. The ODF maps were reconstructed according to the projection of equal area. According to this method, the actual ODF of cold-rolled TA7 alloy sheet was analyzed. The results show that the texture analysis is completely equivalent to the original isometry; this method can clearly establish the relationship between the inverse pole figure and the ODF graph. The use of equal area projection method makes the texture quantitative easy and easy.
