Abstract

A new technique, based on the combination of time-resolved X-ray diffraction (TRXRD) and high-temperature laser scanning confocal microscopy (LSCM), was developed for direct observation of morphological evolution and simultaneous identification of the phases. TRXRD data and LSCM images under the desired thermal cycles were measured simultaneously. As several observation examples, the microstructural evolutions in the steel materials were observed to investigate the phase transformation kinetics under the thermal cycle including the rapid heating and cooling.
