Non‐linear diffraction strain vs sin2ψ phenomena in specimens exhibiting rolling‐type texture

Non-linearities in measured diffraction strains are frequently observed in textured materials. For the case of textured cold-rolled low-carbon steel sheet specimens the diffraction strain is analysed in its constituents: single-crystallite strain and the orientation distribution function of the crystallites. With only macro-stresses 0.~ and 0"2 taken into account, a satisfactory explanation of practical measurements on these steel specimens is obtained.
