| Summary: | Заглавие с экрана The influence of hydrogen alloying on microstructure and microhardness of high-nitrogen Fe-19Cr21Mn-1.3V-0.8N-0.3C wt. % steel produced by high-pressure torsion (HPT) was investigated. Examination of Xrays diffraction data indicates that hydrogenation of HPT-processed specimens leads to a broadening of X-rays lines and their shifting as result of stacking-faults formation and high residual stresses. Hydrogenation of HPTprocessed steel promotes to gamma-epsilon martensitic transformation. Due to hydrogen-induced phase hardening, the microhardness of the steel increases from 6.5 GPa in hydrogen-free state to 6.8 GPa in hydrogencharged one. After exposure for 170 h. at air condition, the position of X-rays lines became close to one for state after HPT without hydrogen-charging due to release of hydrogen atoms. |
