Diffraction peak indexing using HiSPoD. (a, b) Indexing of a diffraction pattern from a NiTi sample, collected during a high-rate tensile loading (undulator gap 20 mm, exposure time 3.37 µs). The reference diffraction peaks for austenite (white) and martensite (red) phases are superimposed. Cases are shown of the third-harmonic (a) and fourth-harmonic (b) energies. (c) Indexing of 1D diffraction intensity. Blue, red and green indexing bars correspond to the third-, fourth- and fifth-harmonic energies, respectively. Solid indexing bars are for the austenite phase, and dotted bars are for the martensite.
