FIELD: physics, optics.
SUBSTANCE: invention relates to methods of determining physical conditions at which phase transitions in metals and alloys take place. The method is based on joint analysis of the image of fragments of the surface of analysed material and luminance spectra of visible light reflected from the said surface, taken before and after the external physical action causing the phase transition. The analysis results are processed using special computer software.
EFFECT: invention simplifies diagnosis of phase transitions, increases accuracy and degree of automation of processing experimental results.
