Figure 1
Schematic of the self-propagating reactions in metal multilayer foils, which are the focus of this work. The foils transform from initially alternating layers of two metals (represented by A and B here) to a final AmBn intermetallic phase as determined by the overall composition of the starting foil. In order to deduce the proper phase formation sequence in the reactions we collect time-resolved diffraction patterns as the reaction front crosses the (fixed) location of a focused X-ray beam while keeping the exposure/collection time short enough that the beam remains within the reaction zone during the measurement. The beam sizes in our experiments ranged from 60 µm using capillary optics at CHESS to 7 µm using Kirkpatrick–Baez focusing mirrors at APS. |
