Изобрегение относитс к способам измерени физических величин, в частности пористости спеченных материалов.The image refers to methods for measuring physical quantities, in particular the porosity of sintered materials.
Известен способ определени интегральной пористости образца i t заключающийс в -том, что объем изолированного образца определ ют гидровзвешиванием. Однако этот способ трудоемок и с его помощью невозможно определить локальную пористость.A known method for determining the integral porosity of a sample, i t, is that the volume of an isolated sample is determined by hydro-weighing. However, this method is laborious and with its help it is impossible to determine the local porosity.

нической сущности вл етс способ определени зависимости модул упругости, коэффициента внутреннего трени и неусганоысвшей с ползучести материала от температуры 2 заключающийс в том, что испытуемый образец непрерывно нагревают, возбуждают в нем изгибные колебани , воздейству магнитным полем, и с помощью регистрирующей аппаратуры, записывают искомые данные.essence is a method for determining the dependence of the modulus of elasticity, the coefficient of internal friction and the material that is not cushioned from temperature 2, which consists in heating the test sample, excite bending vibrations in it, by a magnetic field, and using recording equipment, record the desired data .
Этот способ также трудоемок и сложен.This method is also laborious and complicated.
Целью изобретени вл етс ускорение и упрощение способа определени интегральной пористости.Поставленна цель достигаетс тем, что измер ют энергию, затраченную на внутре нее трение в образце, и по ее величине суд т о пористости спеченного материала.The aim of the invention is to accelerate and simplify the method of determining the integral porosity. The goal is achieved by measuring the energy expended on internal friction in the sample, and by its magnitude judging the porosity of the sintered material.
