The influence of chemical and technological parameters of materials in the design of objects in industrial design on the example of state facilities

Abstract

The purpose of this study is to generalise the thermodynamic model describing the fragmentation of metals or alloys at integrated project delivery, and to study the features and conditions for the formation of limit (stationary) structures of various types. Thus, a Project Delivery is constructed in the two‐defect model approximation with dislocation density and grain boundaries taken into account, which establishes the conditions for the formation of limit (stationary) structures of different types. In addition, the article studies in detail the evolution of the main structural defects and their interaction during the implementation of the stationary regime, and also establishes the dependence of the type of limit structure formed on the values of landslide deformation and the initial state of the material. It is found that the change of states of the system is of solid‐state phase transformation nature. It follows from the methods of description that the limit (stationary) structure is not immutable, but represents a dynamic equilibrium of the processes of generation and annihilation of structural defects.
