In this book, a systematic study using in-situ experimental techniques and numerical modeling on micromechanical behaviors of a duplex steel was presented. In-situ neutron diffraction measurements and tensile EBSD tests have been carried out to study the micromechanical behavior of a duplex stainless steel of austenite and ferrite under uniaxial loading. A two-phase Self-Consistent model that takes into account of the initial texture, microstructure, thermal residual stress, slip process, work-hardening behavior and texture in both phases has been developed. Using the material parameters that…mehr

In this book, a systematic study using in-situ experimental techniques and numerical modeling on micromechanical behaviors of a duplex steel was presented. In-situ neutron diffraction measurements and tensile EBSD tests have been carried out to study the micromechanical behavior of a duplex stainless steel of austenite and ferrite under uniaxial loading. A two-phase Self-Consistent model that takes into account of the initial texture, microstructure, thermal residual stress, slip process, work-hardening behavior and texture in both phases has been developed. Using the material parameters that are directly derived from the neutron diffraction experiments together with the laboratorial mechanical tests, the model is implemented to simulate the deformation of the duplex steel, so as to elucidate its elastic and plastic anisotropy which is characterized by the grain-orientation-dependent stresses and the phase-to-phase interactions within the material.The model has also been applied to predict rolling textures of the duplex alloy, and the special interest is focused on the modeling of the Brass-type texture for the f.c.c. phase.
