“…Although the slip resistance decreases for all slip systems, the ratio increases with increasing temperature. This result is consistent with the observations reported by Orozco-Caballero et al [18,61] and Lütjering et al [54]. The direct consequence of the increase of slip anisotropy is that the pyramidal mode becomes harder to activate than slip system with increasing temperature.…”

“…When the temperature is increased from RT to 100 or 300°C, internal elastic strains, resulting from the interaction between the grains, appear in the polycrystal and thus generate internal stresses. A thermoelastic formulation has been used to simulate the evolution of thermal stresses associated to the heating at 100 and 300°C [54]. The EPSC scheme is then used to predict the mechanical behaviour of titanium polycrystal under a uniaxial tension for a given temperature.…”

“…Since elastic (c ij ) and thermal (α ij ) coefficients depend on temperature, their evolution with temperature was taken into account through the measurements achieved by Fisher and Renken [55] and Wasilewski [56], respectively. The temperature dependence of these coefficients can be described by a polynomial relation given in [54].…”

Plastic deformation of titanium alloys depends on the temperature and the mechanical loading mode. It is accommodated by a complex mixture of slip and twinning systems. It remains nevertheless unclear which deformation modes are activated in the polycrystal during loading, especially with the temperature. In order to better understand the mechanical behaviour of textured α-Ti, neutron diffraction measurements have been performed to analyse the intergranular strain evolution under tensile tests at different temperatures ranging from ambient up to 300°C.The material has then been characterized from meso-(grain) to macroscopic scales in order to obtain relevant information about the deformation mechanisms governing its global behaviour.An elastoplastic self-consistent approach has been used to explain and interpret the experimental observations achieved under thermomechanical loadings. The model has enabled us to successfully predict the measured macroscopic behaviour and the lattice strain development. The study has also provided a comprehensive data set and a complete description of temperature influence onto the mechanical state and the plastic anisotropy, especially at the mesoscopic level.The evolution of the deformation mode hierarchy and the internal stress fields with the temperature have been determined.

“…The advantage of diffraction methods is that measurements are performed selectively only for the crystallites contributing to the measured diffraction peak, i.e. for the grains having lattice orientations for which the Bragg condition is fulfilled (Greenough, 1949;Gloaguen et al, 2002aGloaguen et al, , 2002b. When several phases are present within a specimen, the measurements of separate diffraction peaks allow the investigation of each phase independently (Amos et al, 0167-6636/$ -see front matter Ó 2010 Elsevier Ltd.

a b s t r a c tDifferent experimental approaches have been performed in order to extract damage at several scales. In this paper two experimental methods are treated. Neutron diffraction coupled with tensile test has been performed to study damage at mesoscopic scale. At macroscopic scale, classical tensile test has been used to extract damage effects, from material hardening evolution. Optical measurements and particular data treatment have been used in order to correct data for the necking phenomenon at large deformation, for each experimental method. Damage process in duplex steels has then been analysed at both macroscopic and mesoscopic scales using scale transition models. Eventually, investigations at those scales have been compared to understand correlation between mesoscopic and macroscopic behaviour of our material.

International audienceAn experimental and theoretical investigation was carried out to study the in-depth distribution of residual stress after a cold-rolling test in a zirconium alloy. Grazing incidence X-ray diffraction was used to analyze the heterogeneous stress field with regard to different diffraction volumes below the surface of the sample. An interpretation of the intergranular stress analysis based on in-depth stress development has been made using an elastoplastic self-consistent model in order to account for the effect of plastic anisotropy. The contribution and the magnitude of both the first- and second-order residual stresses as a function of the penetration depth has been correctly evaluated using information from the model. The results show the complementarity of the methods used
