Determination of the volume fraction of precipitates in a nitrided Fe-0.354Â wt% C-2.93Â wt% Cr model alloy by anomalous small angle X-ray scattering

Anomalous small angle scattering (ASAXS) is a powerful non-destructive technique that can provide characteristic features of nanoscale precipitates such as the volume fraction, and chemical composition. In this paper, the technique is used for the first time to explore nanoscale MN nitrides (M = Cr,Fe) after nitriding of a model iron alloy (Fe-0.354 wt% C-2.93 wt% Cr).
