Master curve evaluation at static and dynamic conditions of loading for cast ferritic steel.

Popis výsledku v původním jazyce

The methodology of master curve (MC) has been applied for assessment of the fracture toughness transition behaviour of cast ferritic steel. Low carbon manganese steel intended for fabrication of large containers of spent nuclear fuel (SKODA) was used forthe analysis. Two locations, surface layer and central part, of the thick-walled plate have been followed in order to evaluate the material fracture resistance of full-scale cask segment. For determining the reference temperature T0, that is taken as abasic material characteristic positioning the MC on the temperature axis the standard (1T) bend specimens were taken. Fracture toughness data were determined for two different loading rates. For dynamic loading two calculation procedures of dynamic fracture toughness determination have been applied, the first one arising from quasistatic approach and the other based on concept of dynamic key curve method. The shift of reference temperature for dynamic loading toward to higher temperature
