Abstract

Le dispositif concerne une sonde pour la détermination des transformations de phase qui se produisent dans les métaux, généralement à des températures élevées, au cours du refroidissement ou du chauffage. Grace à un circuit résonnant (6) approprié, opportunément protégé par une structure refroidie (5) résistante à la chaleur (2) mais perméable au flux électromagnétique, la sonde est sensible aux variations de certaines caractéristiques physiques liées aux transformations de phase qui se produisent dans les métaux.The device relates to a probe for determining the phase transformations which occur in metals, generally at high temperatures, during cooling or heating. Thanks to an appropriate resonant circuit (6), conveniently protected by a cooled structure (5) resistant to heat (2) but permeable to electromagnetic flux, the probe is sensitive to variations in certain physical characteristics linked to phase transformations that occur in metals.
