"Evaluation of hydrogen embrittlement of steels by means of the quantitative methods of structure analysis"@en . "0"^^ . "The proposed project is devoted to the study of hydrogen embrittlement (HE) of steels by means of the quantitative methods of the structure analysis. The study will be focused on carbon steels used in the oil industry and on alloyed CrMo, CrNiMo and MnNiMo steels used in the power and chemical industry. In the both cases, the serious risk of HE exists with all negative consequences. The studied materials will differ in their cleanliness, heat treatment (microstructure) and kind of products (plates, forgings). Hydrogen charging will be performed either electrolytically in acid water solutions or in H2S environments. To estimate the degree of degradation in the presence of hydrogen, tensile tests will be applied or tests according to NACE standards will be performed. The special attention will be paid to the evaluation of HE by means of the quantitative methods of the structure analysis. The main objectives include development of new methods in the field of the quantitative fractography and fractur"@en . . . "1007"^^ . . "11"^^ . "1917"^^ . "11"^^ . . . . .
