METHOD OF PREDICTING METAL RESOURCE OF OBJECT Russian patent published in 2005 - IPC

FIELD: investigating or analyzing material.

SUBSTANCE: method comprises introducing supersonic mechanical pulses of flexible deformation into the metal of the object to be analyzed, receiving the accelerated acoustical response to the pulses as a signal from acceleration pickup that is fed to the personal computer, determining physico-mechanical parameters of the initial metal of the object, analyzing the physico-mechanical parameters of the object metal, such as the friction angle of structural inhomogeneities of natural roughness, analyzing shift of resonance frequencies of the amplitude-frequency spectrum in three frequency ranges, such as relaxation frequency of sliding screw dislocations within the range of 17.83-50.20 Hz, relaxation frequency of sliding edge dislocations within the range of 81.69-433.89 Hz, and absorption frequency within the range of 1899.53-2674.26 when analyzing, determining equivalent friction angles of the structural inhomogeneities of the natural roughness with regard to the value of the angle of the metastable phase of flexible twisting of interatomic and covalent links of crystallographic planes determined by the signal from the acceleration pickup from equations proposed, and determining residual recourse of object metal from the formula presented.

EFFECT: enhanced reliability of predicting.
