Evaluation of J-R fracture resistance characteristics of Korean-made SA 508-Gr.3 RPV steels (I)
Description
J-R fracture resistance tests were performed for 3 different domestic SA508-Gr.3 RPV steels which were classified by refining process. It was observed that fracture resistance decreased as temperature increased from room temperature to 288 .deg. C in common. It was confirmed that decrease of fracture resistance at high temperature was attributed to dynamic strain aging (DSA) through observation of fractography and tensile tests. Fracture resistances of 3 steels were different from each other. Vacuum carbon deoxidizing (VCD) steel was fractured unstably at room temperature. It was deduced that the difference of fracture resistance in the steels of the same specification was due to difference of grain size and microstructure resulting from difference of steel making process
