A comparative analysis of a magnetic method and X-ray diffraction analysis used for estimating the volume fraction of retained austenite in a sheet high-strength economically alloyed steel (applied in the automotive industry), which was subjected to uniaxial tension at different temperatures (+20)-(-40 deg C) until the onset of the strain-hardening stage, is performed. At a low austenite content (<5-8 vol %), the advantage of the magnetic method for estimating the deformation stability of austenite in these steels is shown.
