TRENDS IN CHARPY-V SHELF ENERGY DEGRADATION AND YIELD STRENGTH INCREASE OF NEUTRON-EMBRITTLED PRESSURE VESSEL STEELS.
Abstract
The effects of neutron irradiation on Charpy-V shelf energy and yield strength was examined for three pressure vessel steel compositions: A302-B, A533, and A543. The effects of radiation exposure at low temperature (<300F (149C)) and at elevated temperature (550F (288 C) to 740F (393C)) on the overall notch ductility are documented and compared. Summary plots showing the simultaneous degradation in shelf energy and the increase of yield strength levels broadly illustrate the progressive change from ductile fracture performance to relatively brittle characteristics.
