Determination of composition, residual stress and stacking fault depth profiles in expanded austenite with energy-dispersive diffraction
Article dans une revue avec comité de lecture
Abstract
A methodology is proposed combining the scattering vector method with energy dispersive diffraction for the non-destructive determination of stress- and composition-depth profiles. The advantage of the present method is a relatively short measurement time and avoidance of tedious sublayer removal; the disadvantage as compared to destructive methods is that depth profiles can only be obtained for depth shallower than half the layer thickness. The proposed method is applied to an expanded austenite layer on stainless steel and al- lows the separation of stress, composition and stacking fault density gradients.
