Fracture toughness data for ferritic nuclear pressure vessel materials. Task b: laboratory testing. Final report
A comprehensive testing program on production heats of ferritic nuclear pressure vessel steel has recently been completed and the results from this program are documented in this report. Mechanical tests performed include tensile, drop weight NDTT, Charpy V-notch, instrumented precracked Charpy, static and dynamic compact fracture, and dynamic three-point bend; the temperature range of -150 to 550/sup 0/F was investigated for nine heats of A533B-1 steel, two shielded metal arc weldments (weld metal and heat-affected-zone), and an older A302B steel (ASTM correlation heat). The fracture mechanics tests were performed on specimens up to four inches thick and loading rates ranged from quasi-static to dynamic rates of 500,000 ksi-in 1/2/s. This report also presents the complete history for each heat of material, i.e., mill test reports and welding history, metallography, chemistry, archive lists, and specimen cutting diagrams. (GRA)
