The X-ray diffraction method and the method of transmission electron microophotography are applied to study the phase and structural transformations. The potentiodynamic tests and electrochemical impedance spectroscopy are used to determine the susceptibility of steel to pitting formation in acidic solutions of NaCl. The experimental investigations demonstrate that the martensite phase consists mainly of α′-martensite and its content increases with the level of strains. The interphase electrochemical parameters demonstrate that if the content of the martensite phase is lower than 6% or higher than 22%, then the susceptibility of the material to pitting formation increases with the content of the martensite phase. However, within the range 6-22%, the indicated characteristic is a decreasing function of the content of martensite.
