FIELD: machine engineering. SUBSTANCE: method comprises steps of subjecting a sample to impulse deformation by a single-axis impact loading of the sample with use of an impact machine, having impulse duration 
, where τ impulse duration; h a thickness of the machine; C- speed of yielding front; using as a source of the single-axis impact loading a pneumatic ram, operating with loading rate 30-450 m/s. EFFECT: the method of hardening, being nondestructive one, provides ecological and technological safety, and allows to check parameters of the process. 2 cl, 7 dwg, 4 tbl
