As an object of control there is a process of pressure application upon melt under consideration. In the course of metal pressure shaping the atoms ap-proach takes place at the elimination of some heat so that changes of a value and a speed of pressure applica-tion ensure atom approaches for different distances of elastic repulsive force actions till crystallization begin-ning.
A possibility of accumulation and changes of in-teratomic interaction elastic energy in molten metal is considered as a fundamental basis for the change of metal structure and properties connected with it. The-reupon at the study of the process it is necessary to determine significant factors and their impact upon casting properties and on the basis of the mathematical description to determine laws of control.
In the paper it is shown that pressure application is possible to a melt according to a certain law, before crystallization beginning, at the expense of modern control equipment and automation means use.
This process represents a high significance in the creation of modern systems for manufacturing process control with the purpose of obtaining new kinds of materials with a specified combination of physical-chemical properties.
