English abstract:
Synchrotron has become an essential tool to study averaged internal stresses in the bulk of multiphase materials. In situ investigations reveal the evolution of internal stresses developed during thermal cycling of discontinuously reinforced metal matrix composites (MMCs). The effect of externally applied elastic tensile stresses is also considered. Compressive stresses are produced in the Al matrix during heating and tensile stresses during cooling. Above 200°C, the different creep resistance of the MMCs is related to different relaxation velocities of the residual stresses.
