Purpose

Increase of the probability of non-destructive control of structural- sensitive parameters of solid materials on the basis of differential-thermal analysis.

Methodology

The studies were carried out through the justification of the dependence of the peak temperature on the differential-thermal curves on the physicochemical changes in the molecular structure of solid materials.

Findings

The method of non-destructive control of the molecular structure of solid materials is improved, the distinguishing feature of which is a new sign of suitability for the peak values of the thermodynamic process in solid materials, which made it possible to increase the reliability of the non-destructive control. A statistical norm for deciding on the suitability of solid materials was introduced, which made it possible to organize statistical express control of solid materials under conditions of industrial production of electronic devices.

It contains the researches, which were conducted within the project 0117U007139 «Methods and devices for forming, processing and measuring signals of radio information systems of industrial and military objects», financed by Ministry of Education and Science of Ukraine.
