Description
Изобретение относитс к измерени м теплофизических свойств твердых материалов и предназначено дл использовани в материаловедении при изучении свойств металлов/ сплавов , полупроводников, диэлектриков.The invention relates to the measurement of the thermophysical properties of solid materials and is intended for use in materials science in the study of the properties of metals / alloys, semiconductors, and dielectrics.
Известен способ измерени теплофизических свойств исследуегФах материалов/согласно которому подают тепловой импульс на одну сторону образца, изготовленного в виде составной пластины, и измер ют зависимость температуры от времени наего противоположной стороне 1.A known method for measuring the thermophysical properties of materials / materials according to which a heat pulse is applied to one side of a sample made as a composite plate, and the temperature is measured as a function of time on the opposite side 1.
Однако этот способ требует изготовлени сложного образца из исследуемого материала и материала с известными теплофизическими свойствами (теплоемкостью-;., и коэффициентом температуропроводности) и не позвол ет определить температуропроводность с погрешностью меньше 10 %.However, this method requires the manufacture of a complex sample from the material under study and a material with known thermophysical properties (heat capacity -;., And thermal diffusivity) and does not allow to determine thermal diffusivity with an error less than 10%.
Наиболее близким к предлагаемому вл етс способ комплексного измерени теплофизических свойств твердых материалов, заключающийс в том, что тепловой импульс, энерги которого известна, подают на одну сторону плоского образца и измер ют изменение температуры во времени противоположной стороны и по полученным данным определ ют коэффициент температуропроводности , и теплоемкости 12 .The closest to the present invention is a method of complex measurement of the thermophysical properties of solid materials, which consists in the fact that a thermal pulse, whose energy is known, is fed to one side of a flat sample and the temperature change in time of the opposite side is measured, and the thermal diffusivity is determined from the data obtained and heat capacity 12.
Однако этот способ не позвол ет экспрессно воспроизвести результаты измерений, получить температурную зависимость теп.тэфизических свойств исследуемого материала в ходе одного эксперимента и не обладает внутренним контролем, т. е. не позвол ет независимым образом измерить теплоемкость , теплопроводность и коэффициент температуропроводности.However, this method does not allow rapid reproduction of the measurement results, to obtain the temperature dependence of the thermal characteristics of the material under study in one experiment and does not have internal control, i.e., it does not allow independent measurement of heat capacity, thermal conductivity and thermal diffusivity.
Целью изобретени вл етс сокращение времени при определении темпе ратурной зависимости теплофизических СВОЙСТВ, экспрессное воспроизведение результатов и независимое опре20 деление теплопроводности, теплоемкости и коэффициента температуропроводности .The aim of the invention is to reduce the time for determining the temperature dependence of thermal properties, express reproduction of results and independent determination of thermal conductivity, heat capacity and thermal diffusivity.
