METHOD FOR NONDESTRUCTIVE INSPECTION OF THERMOPHYSICAL PROPERTIES OF STRUCTURAL MATERIALS AND ARTICLES

摘要

FIELD: physics.;SUBSTANCE: according to the disclosed method, the surface of an analysed solid structural material is exposed to a microwave field with frequency of not less than 10 GHz, heating the thermally semi-bounded analysed body. Having information about the power of the microwave generator acting on the analysed object, information about thermal flux from the surface of a circular region, the desired thermophysical properties are determined using mathematical relationships obtained based on model representations of physical properties taking place in the analysed objects when the surface thereof is exposed to a high-frequency electromagnetic field.;EFFECT: high accuracy of obtained data.;3 dwg, 2 tbl
