Textures in Pure Shear Deformed Rock Salt

Texture formation in pure shear deformed rock salt has been studied by neutron diffraction. Thetextures developed are comparable to those of rolled face-centered cubic metals with high stackingfault energy. At room temperature the texture consists of a strong S and copper and a weaker brasscomponent. It is replaced by static and/or dynamic recrystallization by a strong cube and a subordinateGoss component. Comparison of the experimental textures with simulations based on different modelsshows that the low temperature high strain deformation texture can be qualitatively well explainedby the Taylor model using slip on{ 110 }〈 110 〉 ,{ 100 }〈 110 〉and{ 111 }〈 110 〉systems with equalcritical resolved shear stresses. Relaxation with increasing temperature introduces the cube and Gosscomponent, which may represent the nuclei for recrystallization. The study shows that texturesimulations on salt without considering recrystallization lead to misleading conclusions.
