| Embrittlement of Steel Plates and Forgings and Their Weldments by Neutron Irradiation Yoshifumi Nakano, Seimei Karino, Akio Ejima |
|
Synopsis : The change in mechanical properties of heavy section steel plates, forgings, and their welded joints for light water reactor pressure vessels, induced by neutron irradiation, is evaluated by tensile tests, Charpy impact tests, and static fracture toughness tests using compact specimens. The study indicates that the materials tested have low sensitivity to neutron irradiation embrittlement, the increase in Ni content within the range allowed by ASTM specifications does not adversely affect the sensitivity to neutron irradiation embrittlement, and the transition temperature for static fracture toughness K(JIC)=100MPaγm agrees well with that for Charpy impact value of 41J. |
