THE COMPARATIVE RESULTS OF THE TENSILE TESTS OF SPECIMENS MADE OF STEEL 20 USING THE METAL MAGNETIC MEMORY AND ACOUSTIC EMISSION METHODS
(pp. 70-72)

Abstract. The results of the steel specimens' tensile tests, which were performed simultaneously with metal magnetic memory method and acoustic emission diagnostic parameters registration, are adduced in the paper. There are tensile test diagrams –ε describing the mechanical properties of the specimens (yield stress y and tensile strength t), which are compared with the metal magnetic memory method and acoustic emission parameters. As a result of performed tests, the identical energy dependence of magnetic and acoustic parameters with the mechanical properties of metal (yield stress and tensile strength) was established. It was discovered that there is possibility of complementarity metal magnetic memory method and acoustic emission when used in combination in practice.

Keywords: specimen, yield stress, tensile strength, metal magnetic memory method, acoustic emission method, tensile test.
