ABSTRACT
The paper deals with examination of relation between the hardness and the size of plastic zone during the tensile loading. UCI (Ultrasonic Contact Impedance) micro-hardness method was used for hardness measurements. Deformation was evaluated by non-contact extensometry method – videoextensometry. The result present existence of the power lawl relation between hardness and plastic deformation: HV = HV(p)+ kE^a. Hot rolled sheet and thin automotive sheet were investigated.
