Abstract : The report presents the initial progress of a research program to investigate the fracture toughness of heavy section steels as influenced by mechanical constraint and through-thickness metallurgical variations. The fracture toughness of the steels studied are defined primarily by means of the Dynamic Tear (DT) test developed by NRL for characterizing a wide variety of commercial steels. The present report describes the initial evaluations of two thicknesses of A-533B reactor grade steels and includes Charpy-V as well as DT results. The 6-3/8-in. thick A-533B Class II material is part of an existing NRL program while the 12-in. thick A-533B Class I material is part of the Atomic Energy Commission's Heavy Section Steel Technology Program.
