Abstract
The process of the formation of the martensite phase in tensile tests of austenitic steel was studied by the scanning contact potentiometry method (SCP). Steel sample, that was produced from “EI847” steel, was tensile tested at room temperature over a wide range of loads (50–60 MPa) for several weeks at intervals of one to five days when the sample was unloaded. Three stages of formation of the martensite phase have been found. Potentiograms and spectrograms were constructed and analyzed in the stress range from 150 to 650 MPa. The method for spectral analysis of potentiograms has been developed, which improves the image quality of reflections of structural inhomogeneities.
