METHOD FOR COMPARATIVE EVALUATION OF PROPERTIES OF MATERIALS FROM PARAMETERS OF REBOUND DIMPLE IN INDENTER TRACE DURING PENDULUM SCRIBING Russian patent published in 2015 - IPC G01N3/46 

FIELD: physics.

SUBSTANCE: method comprises one-time loading of material with indentation by pendulum scribing; measuring the scribing results; establishing a relationship between the measurement results and investigated physical-mechanical properties of materials and predicting operational properties of the compared materials; implementing a pendulum scribing mode, where an indenter at the beginning of interaction with a sample forms a rebound dimple on the surface of said sample; measuring parameters of the dimple and determining physical-mechanical and operational properties of the compared materials.

EFFECT: simplified method of evaluating physical-mechanical properties of material with pendulum indentation, predicting efficiency of using compared materials in identical operating conditions by enabling ranking thereof according to the value of a parameter measured during inspection.
