Subject of study - to solve the scientific and technical problem: on the basis of theoretical and experimental studies to develop a method of quantifying fracture of brittle inclusions in the parameters of acoustic emission (AE) elastic waves. Established physical and mechanical properties of materials with brittle inclusions (chemical composition, strength properties, geometric dimensions, etc.) Proposed analytical dependens for determination of lamellar forms brittle inclusions size taking into account the time relaxation of stresses during their fracture. This will create a methodology to assess the early stages of the fracture of structural elements, which are made of structural alloys containing inclusion.
