Information × Registration Number 0119U101187, ( 0220U101016  0221U100304  ) R & D request Title Development of the methodological basis for technical state assessment and secure lifetime justification of structural elements of the increased danger objects in hydrogen-contained environments Head Dmytrakh Ihor M., Registration Date 21-03-2019 Organization Karpenko Physico-Mechanical Institute of NASU popup.description1 Determination of the influence of hydrogen concentration in metal (volume and local, near of high-stressed zones) on the change of its deformation mechanism (plasticization – embrittlement), and determination of critical (threshold) concentrations values for low-alloyed structural steels of ferrite and ferrite-pearlite classes. Development of new criteria for evaluation of their strength and resistance to fracture in hydrogen-containing environments, as well as new methods for engineering calculations of reliability and durability of pipelines and pressure vessels. popup.nrat_date 2024-12-10 Close
