A method for nondestructive proximate testing of plastic deformations in metals and alloys by measuring the differential thermal emf is considered. Using an instrument that was developed for this problem, thermal emf measurements were performed on several specimens of steels of different types on which notches were made as zones of expected localization of plastic deformations. During extension of specimens, the thermal emf was measured in the plastic-deformation zone. A linear decrease in the thermal emf was observed; the maximum change occurred just before specimen frac-ture.
