研究了变形量达到93%的AlMn1合金的真横轧和伪横轧（变形量达到总变形量的一半后只改变一次轧制方向）。从ODF的角度研究了织构的形成。在真正的交叉轧制（多阶段轧制）后，在（011）[322]附近发现了一个强双分量理想取向，其最大密度可达随机的60倍。伪交叉轧制（两段轧制）产生的变形织构强度较弱，但仍很强，最大密度可达随机的20倍，介于单向和真交叉轧制之间。在这两种情况下，随着变形程度的增加，原有的立方体织构不断减少。
True cross-rolling and pseudo cross-rolling (with only one change of the rolling direction after half of the total deformation degree) was investigated in an alloy AlMn1 up to 93% deformation. The texture formation was studied in terms of ODF. After true cross-rolling (multi-stage rolling) a strong two-component ideal orientation near (011)[322] was found with maximum densities up to 60 times random. Pseudo cross-rolling (two-stage rolling) resulted in weaker, but still strong deformation textures with maximum densities up to twenty times random which were intermediate between unidirectional and true cross-rolling textures. In both cases, the originally present cube texture decreased continuously with increasing deformation degree.
