title: Effect of external stress on the Fe-Cr phase separation in 15-5 PH and Fe-15Cr-5Ni alloys.
abstract: The effect on Fe-Cr phase separation of a uniaxial stress during thermal ageing at 425 °C is investigated on a Fe-15Cr-5Ni steel, a model alloy of commercial 15-5 PH steel. The applied stress is shown to accelerate the ageing kinetics, and influence the morphology of Cr rich domains. A dependence of the phase separation decomposition kinetics on the relative orientations of the load and the crystal local orientation has also been observed.
