Experimental studies of changes in the volume of crystallizing metal under high pressure

The influence of pressure on the formation of the structure and properties of metals deserves attention both from a scientific point of view and in a purely applied aspect. A scientific and methodological approach has been proposed to study the crystallization process, which involves measuring the volume of crystallizing metal under high pressure conditions. It was found that to compensate for the decrease in the volume of the metal during crystallization, it is necessary to adjust the pressure value to the metal's resistance to “shear deformations”, which ensures the delivery of individual atoms to crystals in which structural defects occur. The measurement results were used in the development of pressure application schemes, as well as in calculations of parameters of research and industrial equipment.
