The image shows the intensity of diffraction intensity of phase evolution during weld cooling measured with time-resolved X-ray diffraction technique using synchrotron radiation. The image shows the formation face centered cubic phase (austenite) emanating from liquid first. This phase then transforms to body centered cubic (ferrite) phase on cooling further.
The data were read from binary .spe file created by detectors using GBLoadwave and then plotted as image file.
