The energy stored in grains during cold rolling has been evaluated in a Fe-53%Ni alloy and in a duplex stainless steel using neutron diffraction. The measurements of diffraction peak broadening were undertaken to study the influence of stored energy on mechanisms that govern the development of the cube texture in a heavily cold rolled Fe-Ni alloy. The results suggest that the energy difference between the cube and the other main orientations increases with reduction and thus promotes the cube growth during recrystallization. It appears that such a method is relevant for a two-phase material. Furthermore, the energy levels found in the two phases are in good agreement with the strain measurements found in the literature. The austenite phase stores more energy than the ferrite one.

A quantitative comparison of the errors introduced by several methods for the reproduction of the crystallographic orientation distribution function from poles figures is presented. The harmonic, ADC, WIMV and component methods have been employed in the characterization of the deformation and recrystallization textures of a Fe-50% Ni alloy in order to investigate the accuracy associated with each one of these methods. To carry out this study, experimental and synthetic pole figures have been used as input data. The strong and weak points of each method are examined showing that the iterative discrete methods (ADC and WIMV) are better suited for the reproduction of the texture function in the present case. In comparing these two discrete methods, it is evidenced that the ADC method reproduces more accurately both the experimental and synthetic texture functions over the entire range of texture sharpness considered.
