METHOD OF VISCOUS AND BRITTLE CONSTITUENTS DEFORMATION IDENTIFICATION IN IMPACT BENDING TESTS Russian patent published in 2017 - IPC G01N3/30 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the scientific research methods field, used in identifying the products destruction reasons, as well as used during the properties of solid bodies and mechanisms of its destruction study, and can be used in chemical, petrochemical, energy, engineering and metallurgical industries, for quality control and assessment of the materials operability at the transport sites, while predicting the operational reliability of parts and machines components of production purposes manufactured from them. As the parameter describing the nature of the fracture surface, the characteristic surface area is used Sr - the surface topography area referred to the field of view area.

EFFECT: possibility of the objective determination the viscous and brittle constituents ratio in steels fractures.
