Phase Separation in Lean-Grade Duplex Stainless Steel 2101

Creator:: Garfinkel, David A., Poplawsky, Jonathan D., Guo, Wei, Young, George A., and Tucker, Julie D.
Abstract:: The use of duplex stainless steels (DSS) in nuclear power generation systems is limited by thermal instability that leads to embrittlement in the temperature range of 204°C to 538°C. New lean-grade alloys, such as 2101, offer the potential to mitigate these effects. Thermal embrittlement was quantified through impact toughness and...

An atom probe perspective on phase separation and precipitation in duplex stainless steels

Creator:: Guo, Wei, Garfinkel, David A., Tucker, Julie D., Haley, Daniel, Young, George A., and Poplawsky, Jonathan D.
Abstract:: Three-dimensional chemical imaging of Fe–Cr alloys showing Fe-rich (α)/Cr-rich (α') phase separation is reported using atom probe tomography techniques. The extent of phase separation, i.e., amplitude and wavelength, has been quantitatively assessed using the Langer-Bar-on-Miller, proximity histogram, and autocorrelation function methods for two separate Fe–Cr alloys, designated 2101 and 2205....

Appendix D - Stable Isotope Data.pdf

Creator:: Hornung, Jonathan P.
Abstract:: Deep-sea bamboo coral (Isidella sp.) SE000901A from the southern Oregon coast (water depth 1048m) provides a high-resolution record of variability of North Pacific Intermediate Water (NPIW) and carbon rain to the sea floor, related to coastal upwelling, from 1808 to 2000AD. Counting of annual layers in magnesium to calcium (Mg/Ca)...

Quantification of advection and dispersion in lateral subsurface flowpaths at the hillslope-scale

Creator:: Victory, Nichole I.
Abstract:: It is becoming increasingly important to understand fundamental hillslope-scale hydrological processes. Most hillslope-sale transport experiments have generally focused on conceptual findings or other aspect of flow behavior, rather than the quantification of the mass transport mechanisms of advection and dispersion. When the velocities have been quantified, dispersion has been mentioned...

Multivariate geostatistical analysis of groundwater contamination by pesticide and nitrate

Creator:: Smyth, Jeffrey D.
Abstract:: A field study was conducted to determine the applicability of multivariate geostatistical methods to the problem of estimating and simulating pesticide concentrations in groundwater from measured concentrations of nitrate and pesticide, when pesticide is undersampled. Prior to this study, no published attempt had been made to apply multivariate geostatistics to...

Experimental design of physical aquifer models for evaluation of groundwater remediation strategies

Creator:: Humphrey, Mark D.
Abstract:: Groundwater resources have become seriously threatened due to improper use by industrial, municipal, and even public sectors. Widespread contamination of aquifer systems has jeopardized human health and the environment and methods for restoring these systems are needed. Biological and chemical in situ remediation, where contaminants are degraded within the natural...

Assessing groundwater vulnerability to contamination using finite element modeling and geographic information systems

Creator:: Rea, Alan H.
Abstract:: A method was developed for assessing the vulnerability of groundwater to contamination from contaminant sources at the soil surface, using a numerical groundwater flow model linked to a digital map database. The method was applied using the pcARC/INFO Geographic Information System (GIS) to input, store, and manipulate base maps, resulting...

Engineering a Profiling System for a Robotic Oceanographic Surface Sampler

Creator:: Shannon, Robert J.
Abstract:: ROSS (Robotic Oceanographic Surface Sampler) is an autonomous boat, equipped with oceanographic sensors, used for studying the ocean’s surface. One of its advantages over traditional research vessels is its ability to sample near glaciers, an area too dangerous for manned ships. In order to properly ascertain deep ocean heat’s effect...

Tide-topography coupling on a continental slope

Creator:: Kelly, Samuel M.
Abstract:: Tide-topography coupling is important for understanding surface-tide energy loss, the intermittency of internal tides, and the cascade of internal-tide energy from large to small scales. Although tide-topography coupling has been observed and modeled for 50 years, the identification of surface and internal tides over arbitrary topography has not been standardized....
