| সংক্ষিপ্ত: | Заглавие с экрана In present study, the regularities of hydrogen embrittlement in specimens of high-nitrogen chromium-manganese steel with different densities of intergranular and interphase (austenite/ferrite) boundaries and the volume fraction of ferrite are studied. It was shown that increase of the temperature of solid solution treatment decreases the density of intergranular and interphase (austenite/δ-ferrite) boundaries and increases in the volume fraction of ferrite. The changes in the density of boundaries and ferrite volume fraction lead to a change in the susceptibility of steel to hydrogen embrittlement and hydrogen-assisted fracture micromechanism. An increase in the density of intergranular and interphase boundaries results in decrease in the hydrogen-affected loss of plasticity. |
