Textures in Pure Shear Deformed Rock Salt
Texture formation in pure shear deformed rock salt has been studied by neutron diffraction. The textures developed are comparable to those of rolled face-centered cubic metals with high stacking fault energy. At room temperature the texture consists of a strong S and copper and a weaker brass component. It is replaced by static and/or dynamic recrystallization by a strong cube and a subordinate Goss component. Comparison of the experimental textures with simulations based on different models shows that the low temperature high strain deformation texture can be qualitatively well explained by the Taylor model using slip on , and systems with equal critical resolved shear stresses. Relaxation with increasing temperature introduces the cube and Goss component, which may represent the nuclei for recrystallization. The study shows that texture simulations on salt without considering recrystallization lead to misleading conclusions.
