Description
Summary:The results for the test of a TimePix hybrid detector as a tool for measuring and imaging in real time dynamics of phase transitions in metal alloys under heating or cooling are presented. The X-rays ( ~ 10 keV) experimental setup explored for the diffraction studies at the Institute for Problems of Material Science NASU (Kyiv) is briefly described. An evolution of the diffraction maxima position (~ 20 μm accuracy) of the scattered X-rays was ob-served with exposures from a few dozen to a few hundred milliseconds under heating or cooling of the samples of Armco iron at a rate of 100 to 250 C/s. Data for the phase transitions (alpha-, gamma-phases observed) during heating/cooling (20 - 1250 °C) using the X-ray diffraction were measured.
