Abstract

The results of cyclic tests of  08Kh18N10T structural steel are presented. The tests were carried out using the accelerated Locati method. The experimental data obtained showed that cyclic deformation of austenitic steel leads to the formation of deformation martensite, as indicated by the results of X-ray phase examination of the sample. The study of the microstructure of steel also indicates structural and phase transformations occurring in steel. The eddy current signal was measured on the test sample before and after the tests. Changes in the phase and amplitude of the eddy current signal occurring after the tests indicate the possibility of using this method to determine the formation of deformation martensite in austenitic steel.
