title = "Neutron diffraction study of elastoplastic behaviour of Al/SiCp metal matrix composite during tensile loading and unloading",
abstract = "The aim of the present work is to study effects occurring during elastoplastic deformation and unloading of Al/SiCp metal-matrix composite material. We have measured lattice strains for both phases independently using two separated diffraction peaks (the {111} reflections of Al and SiC) during in situ tensile testing. Lattice strains were measured in the direction parallel to the applied load. The results were compared with an elastoplastic model in order to find parameters determining the plastic deformation of the Al matrix (critical resolved shear stress and hardening parameter). We have found that during initial deformation relaxation of the thermal stresses occurs in both phases. Afterwards, the distribution of strains measured during the in situ test and unloading of the sample agree very well with self-consistent model predictions.",
