The stress partitioning between phases, phase stress relaxation as well as origins of Al/SiCp composite strengthening arestudied in the present work. In this aim, the measurements of lattice strains by neutron diffraction were performed in situ duringtensile test up to sample fracture. The experimental results were compared with results of elastic–plastic self-consistentmodel. It was found that thermal origin phase stresses relax at the beginning of plastic deformation of Al/SiCp composite. The evolution of lattice strains in both phases can be correctly simulated by the elastic–plastic self-consistent model onlyif the relaxation of initial stresses is taken into account. A major role in the strengthening of the studied composite plays atransfer of stresses to the SiCpreinforcement, however the hardness of Al metal matrix is also important.
