Scanning X-ray Diffraction Microscopy (SXDM, aka ptychography) produces phase and absorption contrast images at high spatial resolution, well below the incident beam size(1). The experimental conditions for SXDM are close enough to X-ray Fluorescence Microscopy (XFM) that they are readily combined into a single simultaneous measurement(2-5). However, SXDM has additional coherence and...
The 55Al-Zn-1.6Si alloy is widely used in hot-dip galvanizing to coat steel and displays a multilayered microstructure (steel substrate/intermetallic compound (IMC) layer/coating overlay) that offers protection from corrosion. Trace level (less than a few tens of ppm) V and Cr are hypothesized to influence the corrosion performance of the coated steel via localized segregation. This work...
