Determination of the volume fraction of precipitates in a nitrided Fe- 0.354 wt% C-2.93 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 char- acteristic 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)
