Abstract: The thermophysical properties (specific heat, thermal diffusivity, thermal conductivity, linear thermal expansion coefficient, density) of 12% chromium ferritic–martensitic steels EK-181 (RUSFER-EK-181) and ChS-139 and the structure–phase transformations that occur in them upon heating and cooling in the temperature range 20–1100$^\circ$C are studied. The temperatures of the start and finish of the $(\alpha\to\gamma)$ and $(\gamma\to\alpha)$ transformations in these steels and the Curie temperature are determined by differential scanning calorimetry. Peaks in the temperature dependence of the specific heat and jumplike changes in the linear thermal expansion coefficient and the density and the minimum of thermal diffusivity are detected in the $(\alpha\to\gamma)$ transformation range. Specific heat peaks, thermal conductivity minima, and inflection points in thermal diffusivity curves are also observed near the Curie temperature.
Keywords: Differential Scanning Calorimetry, Differential Scanning Calorimetry Curve, Linear Thermal Expansion Coefficient, Transformation Range, Intercritical Temperature Range.
