(a)–(c) Absolute shift (filled arrows) and splitting (empty arrows) of the 333/511 diffraction line for an austenitic steel. The line position
E333/5110 = 64.3 keV for the strain-free lattice corresponds to a diffraction angle 2θ = 16° (cf. Table 1). Diagram (d) shows the absolute shift of the 333 and 511 contributions as a function of sin2ψ according to equation (19) and their relative shift against each other (gray area between the straight lines) according to equation (20). The calculation was done assuming the Eshelby–Kröner grain interaction model. |
