cD - HcM)/C(Hc), where HcD – value of coercitive force in sample, with deformation corresponding to first inflection point on graph of "true stresses – value of relative plastic deformation to degree ½", HcM is maximum value of coercitive force in maximum loaded measurement zone on article, C(Hc)=(HcM – Hc0)/T – rate of change of coercive force in time, T – time of operation of article until test moment, Hc0 – value of coercitive force on sample at zero degree of deformation.;EFFECT: invention can be used in nondestructive evaluation of service life of steel products after long service life.;1 cl, 2 dwg, 2 tbl"/>
