Abstract

L'invention concerne la métallurgie Le procédé faisant l'objet de l'invention est caractérisé notamment en ce qu'on mesure l'accroissement DELTA T de la température du métal ou de l'alliage en cours de refroidissement par rapport à la température maximale Tmax relevée durant le cycle de mesure de la température, et qu'on calcule le seuil de durée du palier de température tau en tant que fonction de la température du métal ou de l'alliage en cours de refroidissement, de l'accroissement de cette température par rapport à la température maximale relevée durant le cycle de mesure de la température, et du temps écoulé depuis le début du cycle de mesure de la température. L'invention peut être utilisée en particulier dans l'analyse thermographique des transformations de phase ayant lieu dans les métaux et les alliages pour déterminer les températures de transformations de phase.
