Some characteristics of early stages of stress corrosion cracking

Autor: E. P. Simonen, R. H. Jones

Publikováno v: Journal of Nondestructive Evaluation. 15:121-127

Environment-induced crack growth generally progresses through several stages prior to component failure. Crack initiation, short crack growth, and stage I growth are early stages in crack development that are summarized in this paper. The implication

Radiation effects on time-dependent deformation: Creep and growth

Autor: E. P. Simonen

Publikováno v: Metallurgical Transactions A. 21:1053-1063

Observations of irradiation creep strain as well as irradiation growth strain and related microstructures are reviewed and compared to mechanisms for radiation effects on time-dependent deformation. Composition, microstructure, stress, and temperatur

Effects of Helium on Void Swelling in Vanadium

Autor: E. P. Simonen, J. L. Brimhall

Publikováno v: Nuclear Technology. 29:378-383

Void formation and swelling were studied in nickel-ion-bombarded vanadium, both with and without the presence of helium. Helium has a significant effect on void nucleation when the defect generation rate is low. At high defect generation rates, heliu

Irradiation effects on substructure -related to irradiation softening

Autor: J. L. Brimhall, E. P. Simonen

Publikováno v: Radiation Effects. 101:255-267

The evolution of the dislocation microstructure during irradiation of a deformed Fe-2 1/4 Cr-1 Mo ferritic alloy was characterized by two competing processes. At low temperature, the dislocation density increased due to loop formation and interaction

Lengthening kinetics of ferrite and bainite sideplates

Autor: H. I. Aaronson, E. P. Simonen, Rohit Trivedi

Publikováno v: Metallurgical Transactions. 4:1239-1245

The rate of lengthening of ferrite and bainite sideplates and the radius of curvature of the plate edges were measured as a function of reaction temperature in three Fe-C alloys. These data were analyzed on the basis of an equation due to Trivedi. Th

Capillarity Effect at an α/β Brass Interface

Autor: E. P. Simonen, R. Trivedi

Publikováno v: Metal Science. 8:274-276

Recently, Purdy has properly emphasized the importance of non-ideality of the solid solutions in calculating the influence of interface curvature on the β → α phase transformation in brass. Particularly important is his result that a linear relat

PNL Technical Review of Pressurized Thermal Shock Issues Supplement 1: Technical Critique of the NRC Near-Term Screening Criteria

Autor: P. J. Pelto, E. P. Simonen, S.H. Bian, L. T. Pederson, W. J. Apley, D. L. Stevens, F. A. Simonen

Pacific Northwest Laboratory (PNL) provided a technical critique of the draft report, NRC Staff Evaluation of Pressurized Thermal Shock, dated September 13, 1982. This report provided the basis for the NRC near-term regulatory position on pressurized
