... to join components in the power and nuclear industry. The thermal cycle, during the GTAW process, produces different types of microstructures that affect the material's mechanical properties. The objective of this work was to study the effect of corrosion testing at supercritical water conditions...

...Lucia Rozumová; Lukáš Košek; Jan Vít; Anna Hojná; Patricie Halodová Development of liquid lead cooled nuclear systems requires consideration of compatibility issues with the construction materials. In order to understand the corrosion or passivation behavior of the 316 L austenitic stainless steel...

...M. Pazderová; L. Rozumová; L. Košek; A. Hojná Heavy liquid metal (HLM) cooled systems are under wide investigation and development. The technology needs to study the materials corrosion, which has a different progress than corrosion caused by aqueous media. Improvement of the corrosion resistance...

...J. Veselá; P. Mareš; P. Zahrádka; J. Patera This article describes methods suitable for crack detection on low pressure steam turbine blades, not including the blade root. These cracks, which are initiated in the corrosion pitting, can cause serious damage to the steam turbine blade leading to its...

.... The coated alloy was tested for oxidation at 1250 °C, and corrosion in liquid lead-bismuth eutectic (LBE) alloy at 875 °C for prolonged duration. The silicide-coated alloy showed superior oxidation and LBE corrosion resistance at high temperatures. The alloy was found to be a promising material for coolant...

... of water density between ∼150 and 600 kg/m 3 . The in situ formation of H 3 O + by the generated recoil protons was shown to render the “native” track regions temporarily very acidic (pH ∼ 1). This acidity, though local and transitory (“acid spikes”), raises the question whether it may promote a corrosive...
