Fig. 4. 3D representation and corresponding 2D projection of WAXS pattern intensities plotted as a function of time and the momentum transfer Q recorded in the AST (10,800 cycles between 0.6 and 0.95 VRHE at a scan rate 1 V s−1) for (a) oh-PtNi(RhMo) octahedra and (b) PtNi octahedra. Results from Rietveld refinement analysis in terms the evolution of (c) the lattice constant, (d) relative lattice constant variation and (e) coherent domain size.
