摘要
FIELD: mechanical engineering. SUBSTANCE: method is based on monitoring of beginning of initial plastic deformation and lies in magnetization of metal in zone of imprint in process of impression of indenter, in establishment of dependence " impression force- magnetization ". Moment of beginning of initial plastic deformation is determined by emergence of residual magnetization after unloading of indenter or by start of change of dependence " impression force-magnetization which considerably increases accuracy of determination of mechanical properties of metal. EFFECT: increased accuracy of determination of mechanical properties of metal. 2 cl
