Characterisation of the fracture properties in the ductile to brittle transition region of the weld material of a reactor pressure vessel KU Leuven
This work presents the results of the fracture characterisation of the weld material of a nuclear vessel, currently in service, in the ductile to brittle transition region. The tests consisted of Charpy impact and tensile tests, performed in the framework of the surveillance programme of the plant. Moreover, in the context of this research, KJc fracture toughness tests on pre-cracked Charpy V notch specimens (evaluated according to the Master ...
