Diffraction elastic constant for (a) ferritic and (b) austenitic steel, calculated by means of equations (14a ), (14b )–(16a ) and (16b ) for the grain interaction models of Reuss (R), Voigt (V) and Eshelby–Kröner (K). The framed reflections hkl lie in the vicinity of the model-independent orientation . rK denotes the Reuss fraction in the Eshelby–Kröner DEC model. The single-crystal elastic moduli sij were taken from Landoldt–Börnstein (1984 ). |
