FRACTURE DEVELOPMENT AND MATERIAL PROPERTIES IN PVRC-PENN STATE PRESSURE VESSEL; FATIGUE-CRACK PROPAGATION AND FRACTURE STUDIES OF A PRESSURE-VESSEL STEEL TEMPER EMBRITTLED TO SIMULATE IRRADIATION DAM

scope:
A characterization of materials was conducted in relation to the terminal, burst-type, failure of a PVRC pressure vessel of A212-A (now A515 Gr. 60) steel at 110F. Materials were characterized with respect to chemical composition, tensile properties, fracture toughness including Charpy-V and Tear Energies, Drop-Weight NDT, micrography and electron fractography. The initiation and growth of a 34-in. long fatigue crack was shown to be caused by mechanical aspects rather than material deficiencies and the plastic-instability burst, brittle run, and crack arrest were in complete accord with the Fracture Analysis Diagram.
