METHOD OF DETERMINING RESISTANCE OF DEFORMATION OF METAL MATERIALS WHEN INDENTED BY A CONE Russian patent published in 2020 - IPC G01N3/42 

FIELD: measurement.

SUBSTANCE: invention relates to the field of measurements and, in particular, is intended for investigation of change of mechanical characteristics of materials, after plastic or thermal hardening, by method of indenter introduction at static load. Summary: there are used thin sections prepared from non-reinforced and hardened materials for zone of indenter introduction, indentation mechanism, indenter in form of cone and means of measurement of impression. Conical tip is successively introduced into the surface of sections of non-reinforced and hardened materials by static load of a fixed value, measurement of geometric parameters of prints on a section of non-reinforced and hardened materials and determination of resistance of deformation of hardened material is carried out using the formula. Introduction is carried out with a conical tip with the same test load for non-reinforced and hardened materials.

EFFECT: technical result is reduction of labor intensity and high accuracy of method, broader functional capabilities of method and field of use thereof.
