Texture measurements convey data about different formation or processing routes suffered by natural or man made materials. The information is somehow collapsed in a time and space locus in such a way that interpretation is only possible by considering the interplay of those different mechanisms. Being the phenomena complicated by themselves, their combined action is most of the times only understandable by a careful computer simulation research. The current presentation shows experimental results obtained by different diffraction techniques on a few model and technological materials. The materials include metals, alloys, composites, rocks and biological materials. By computational simulations the different thermomechanical processes are included to achieve a fairly good understanding of their complex inter-relationship.           The studied materials include copper and its brass like alloys, low carbon steels, Cu-Al and Fe-Cu powder composites, Fe-Mn-Si and Al-Cu-Ni shape memory alloys, biological carbonates, etc.           The phenomena included in the simulations are crystalline elastic and plastic deformation, recrystallization phenomena and phase transformations. They are combined in computer simulation codes and their results are useful for the interpretation of texture experiments and analysis of the processing routes.
