In this work the parameters characterizing the individual elastoplastic mechanical behaviour of each phase in austeno-ferritic duplex stainless steels are determined by using X-ray diffraction during a uniaxial tensile test. The interpretation of the experimental data is based on the diffraction elastic constants calculated by the self-consistent model taking the anisotropy of the studied materials into account. The elastoplastic model is used to predict the evolution of the internal stresses during loading, and to identify the critical resolved shear stresses and strain hardening parameters of the material. The effect of the chemical composition on the individual elastoplastic behaviour of the studied phases is established by comparing results from three different samples. Finally, the X-ray diffraction results are compared with those previously obtained by using neutron radiation. (c) 2006 Published by Elsevier B.V.
