FIELD: investigating or analyzing materials. ^ SUBSTANCE: method comprises setting a specimen to be analyzed between two buffer members made of a material with known thermophysical properties and provided with heater and temperature sensors. After the pulse heating of the specimen with a point heater, the signals from the temperature sensors are digitized and sent to the computer which plots dynamic pattern of thermal wave propagation in the material and calculates thermal conductivity and diffusivity of the material depending on direction. ^ EFFECT: enhanced efficiency of determining. ^ 2 cl, 3 dwg |
