Abstract:
Low carbon low alloyed TRIP steel with partial substitution of silicon by aluminium was thermo-mechanically treated to obtain a multiphase microstructure typical for TRIP steels. The processing consisted of soaking at 900°C and two compressive deformations applied during the cooling to the isothermal hold temperature of 425°C. [..]

Abstract:
The application of new materials in the power units of new generation, which are able to work at ultra-supercritical parameters of steam (T ≥ 620-650 °С, Р = 25 - 35 MPa), can increase their efficiency up to 41-44 % and decrease the amount of harmful emissions. The aim of the present research was to investigate the major structural changes in new Re-containing steel during ageing at temperature of 650 °C. [..]

Abstract:
Thermal annealing is a proven material treatment method applicable to WWER type reactor pressure vessels with the aim of prolonging their operational lifetime. However, reactor pressure vessel internals of nuclear power plants are exposed to more severe operating conditions (high pressure and temperatures, higher neutron flux, corrosion environment), which cause gradual degradation of their mechanical properties.

Abstract:
One of the main concern in the development of the Gen IV lead-cooled fast reactors (LFRs) is the compatibility of the candidate structural steels and cladding materials with the heavy liquid metal (HLM). Structural materials compatibility in conditions relevant to plant operation is of primary importance to safety. [..]

Abstract:
The susceptibility to hydrogen embrittlement of a dual-phase steel DP600 with ferritic-martensitic microstructure was studied on previously hydrogenated samples by slow strain rate tensile tests (SSRT). The samples were subjected to electrolytic hydrogen charging in 0.05M sulfuric acid solution with the addition of KSCN at a current density of 1 and 5 mAcm-2 during 4, 8 and 24 hours. [..]
