Abstract

While manufacturing and exploitation of different materials, there could be observed complex physicochemical processes of interaction between their individual components and these components with the environment. Revealing such mechanisms helps to understand their distinct features and optimize technological processes of manufacturing materials with certain characteristics. The solution could be based on interpretation of results of acoustic emission (AE) tests from the perspective of multilevel kinetic model of AE of heterogeneous materials. The article describes the research, the essence of which was to identify systematic changes in the values of the parameters of the AE coefficients included in the model when changing various technological and operational factors on the basis of their operational assessment based on the results of acoustic emission tests.
