The effect of stacking-fault energy on the peculiarities of mechanical twinning development in high-manganese austenitic steels <br />Fe-Mn-Al-C under high-pressure torsion<br />

 Optical metallography, transmission electron microscopy and X-ray diffraction were used to study the peculiarities of structure refinement in high-manganese steels Fe-13Mn-1.3C, Fe-13Mn-2.7Al-1.3C, Fe-28Mn-2.7Al-1.3C (in wt.%) under high-pressure torsion (room temperature, 5-6 GPa, 1 revolution). The effect of stacking fault energy on the peculiarities of twinning development in the studied steels was found out, which is one of the factors that determine the degree of uniformity of the structure through the disk diameter and mechanical characteristics (microhardness) of the steels after torsion.
