Imaging domain dynamics by combined XRD-DMA

Understanding the fundamental atomic-scale\ud processes responsible for the bulk physical\ud properties of solids has long been the aim of\ud structural physics. Historically, there has been a\ud strong emphasis on the understanding of the\ud properties of crystalline materials from a structural\ud crystallographic perspective. The majority\ud of this work has, of course, focused on the\ud information that can be gained from Bragg\ud scattering of X-rays. The development of large\ud linear and area detectors over the last decade\ud has, however, opened up the way for rapid\ud analysis of both diffuse and Bragg scattering\ud over large volumes of reciprocal space.\ud Over this period methods have been developed\ud for systematically exploiting positionsensitive\ud detectors with thousands of detection\ud channels working in parallel, and area\ud detectors that, by parallelisation, are able to\ud collect data at rates six orders of magnitude\ud greater than those of traditional instruments.\ud This means that microstructural and mesoscopic\ud structural features such as transformation\ud twins may now be investigated directly by\ud laboratory X-ray scattering techniques
