EXPERIMENTAL STUDY OF ACOUSTIC EMISSION PARAMETERS DURING CYCLIC TESTING OF METAL PRODUCTS OF ADDITIVE MANUFACTURING
Annotation
The kinetics of destruction of metal products made using additive manufacturing technologies, namely, selective laser melting, is studied. Features of this method of products manufacturing process give rise to various kinds of structural inhomogeneities in the material, which, in turn, affect the strength characteristics. The use of the acoustic emission method in the study of fracture kinetics makes it possible to reveal the initiation of fatigue fracture processes in the material.
