METHOD OF COMPARATIVE EVALUATION OF PROPERTIES OF MATERIALS BY CROSS-SECTION AREA OF BALANCE SCRIBING TRACE Russian patent published in 2015 - IPC G01N3/46 

FIELD: physics.

SUBSTANCE: indenting is performed by balance scribing and scribing results are measured by material strain and destruction parameters. Measured results are referenced to analyzed mechanical properties of materials. Performances features of said materials are predicted by measures results of scribing. Cross-section area S of scribing trace is defined as the sum of component areas, namely S₁+S₂+S₃+S₄, where S₁ is the main material specimen area displaced by indenter, S₂ and S₃ are cross-sections of rolls formed in outline of scribing trace, S₄ is the area of specimen material spalling outside specified areas S₂ and S₃ of rolls. Said area S is used to decide on mechanical and operating features of materials to be ranged in series by variation of properties.

EFFECT: simplified process, enhanced performances.
