Vodíkové křehnutí kostrukční oceli EUROFER 97

Original language description

This article summarizes experimental results of measurements of fracture toughness of EUROFER martensitic steel in presence of hydrogen. Three-point bend method and KLST specimens were used for fracture toughness testing at room temperature and 120°C. The hydrogen effect is shown at the fracture toughness testing at room temperature both of base and weld metals. The J0,2 integral values decrease depending on the hydrogen content in the range of 2 to 4 wppm. The hydrogen content of about 4 wppm decreasesfracture toughness both of base and weld metal to the level 30 KJm-2 or below i.e. approx. 90 % of original values. Hydrogen containing more than 2 wppm manifests itself significantly only in base metal. At the 120°C testing the hydrogen effect manifestitself by lower fracture toughness of base metal specimens only. The J0,2 integral value lowers by about 30 % in the base metal at the hydrogen content approximately 1,2 ? 1,6 wppm.
