Description

(54) СПОСОБ ИЗМЕРЕНИЯ КОЭФФИЦИЕНТА ТЕМПЕРАТУРОПРОВОДНОСТИ ТВЕРДЫХ КОНСТРУКЦИОННЫХ МАТЕРИАЛОВ(54) METHOD OF MEASURING THE COEFFICIENT OF TEMPERATURE CONDUCTIVITY OF SOLID CONSTRUCTION MATERIALS

Изобретение относитс  к изме- рению теплофизических свойств твердых конструкционных мапериалов и предназначено дл  использовани  в материаловедении при изучении свойств металлов, сплавов и т. п. Известен способ определени  коэффициента температуропроводности материалов при котором на одну сторону плоского образца подают тепловой импульс и измер ют температуру в одной точке на его противоположной стороне и по полученным данным определ ют коэффициент температуропроводности С1 .The invention relates to the measurement of the thermophysical properties of solid structural materials, and is intended for use in materials science in studying the properties of metals, alloys, etc. The known method for determining the thermal diffusivity of materials in which a thermal pulse is applied to one side of a flat sample the point on its opposite side and the obtained data determine the thermal diffusivity coefficient C1.

Однако данный способ не позвол ет учесть погрешность измерени , вызванную неравномерным распределением энергии теплового импульса по поверхности образца .However, this method does not allow to take into account the measurement error caused by the nonuniform distribution of the energy of the thermal pulse over the sample surface.

Наиболее близким к изобретению по технической сущности и достигаемому результату  вл етс  способ, согласно которому тепловой импульсThe closest to the invention to the technical essence and the achieved result is the method according to which the thermal impulse

подают на торец образца, выполненного в виде стержн , и измер ют температуру в двух точках на его боковой поверхности , расположенных на одной образующей, и по полученным данным определ ют коэффициент температуропроводности .served on the end of the sample, made in the form of a rod, and the temperature is measured at two points on its side surface located on the same generator, and the coefficient of thermal diffusivity is determined from the data obtained.

Недостатком данного способа  вл етс  отсутствие возможности получитьтемпературную зависимость тепло ,10 физических свойств исследуемого материала в ходе одного эксперимента (чтЬбы измер ть температуропроводность при другой температуре, необходимо разогреть до нее образец, и калориIS метр и дождатьс , когда температурное поле в образце выравн етс , на что уходит значительно больше , чем на непосредственное измерение ).20The disadvantage of this method is the inability to obtain a temperature dependence of heat, 10 physical properties of the material under investigation during one experiment (to measure thermal diffusivity at a different temperature, it is necessary to heat the sample and calories and wait for the temperature field in the sample to equalize which takes much more than direct measurement) .20
