The development of Fe-Cr-C based alloys for high wear and high impact applications

Creator:: Biskey, John Wesley
Abstract:: The structure, hardness, and impact strength of high chromium cast irons was investigated. From the Fe- Cr- C phase diagram, a composition with 74.8 wt% Fe, 21.5 wt% Cr, and 3.7 wt% was selected along the austenite-M₇C₃ eutectic trough. This composition was bracketed by others with slightly different amounts of...

Use of CR-39 for nuclear criticality accident dosimetry and high neutron dose monitoring

Creator:: Tai, Lydia I.
Abstract:: CR-39 foils were irradiated as part of nuclear accident dosimetry experiments using the Godiva reactor at the Nevada National Security Site and the Caliban and Prospero reactors at the Valduc Centre for Nuclear Studies in France. The irradiated foils were chemically etched using the standard Lawrence Livermore National Laboratory process...

Gamma- and beta-ray spectroscopy studies of the radioactive decay of Mn-51 to Cr-51

Creator:: Glibert, Kenneth Malcolm
Abstract:: The decay scheme of Mn⁵¹ has been investigated using gamma-ray and beta-ray scintillation spectrometers and a fast coincidence spectrometer. A half-life value of 46.5 ± 0.2 minutes was determined for Mn⁵¹ which decays predominantly to the ground state of Cr⁵¹ by the emission of positons with an experimentally measured end-point...

Influences of Replacing Cr with Mo in Fe25Co25Ni25Cr25-XMoX High Entropy Alloy Series on the Microstructure and Mechanical Properties

Creator:: Xu, Yifan
Abstract:: Fe25Co25Ni25Cr25-XMoX High Entropy Alloys were fabricated in mini arc-melter and then cast into 4mm diameter cylinders by injection casting technique and 1cm diameter cylinders by water quenching technique. Heat transfer modeling during solidification of FeCoNiCr HEA was simulated. Combining X-Ray Diffraction, Optical Microscopy, Scanning Electron Microscope, Energy Dispersive X-ray analysis,...

Predicting the Effect of Local Conditions on Metal-oxides: Pt/γ-Al₂O₃ Interface and Degradation of α-Cr₂O₃ Passive Film

Creator:: Oware Sarfo, Kofi
Abstract:: Metal-oxides are very important in industrial applications such as thermal barrier coatings, corrosion protection, and heterogeneous catalysis. The wide variety of applications for metal-oxides are derived from the array of properties of metal-oxides. It is, therefore, important to understand and predict the conditions of synthesis and operation to optimize the...

Factors influencing women's enrollment in cardiac rehabilitation : patient and support person perspectives

Creator:: Northrup-Snyder, Kathlynn
Abstract:: Coronary Heart Disease (CHD) accounts for almost 20% of all deaths in the United States and is a leading cause of premature death and disability. The cost for this disease includes not only lost work years, but billions of health care dollars. Women account for almost half of the deaths...

Multi-location analysis for the identification of quantitative trait loci underlying disease resistance against Cephalosporium gramineum and Puccinia striiformis f. sp. tritici by linkage mapping in wheat (Triticum aestivum L.)

Creator:: Vazquez, Maria Dolores
Abstract:: Wheat (Triticum aestivum L.) is one of the major crops produced in the U.S. Pacific Northwest, a region known for its wheat production for international export. Wheat production in the region is threatened by diseases such as Cephalosporium stripe and stripe rust. Cephalosporium stripe is a vascular wilt disease of...

Design of a chemiluminescence photometer and its application to trace chromium (III) analysis

Creator:: Hoyt, Steven D.
Abstract:: The design and construction of a chemiluminescence photometer is described. The design is based on a discrete sample system which has a number of advantages over the previously described flow cell system and centrifugal analyzer. The advantages include simple and inexpensive equipment, small sample size, versatile electronic readout system, and...

Corrosion Resistance of Alloys in Direct-Fired Supercritical CO₂ Power Cycle Aqueous Environments

Creator:: Repukaiti, Reyixiati
Abstract:: Using supercritical CO₂ (sCO₂) as a working fluid has increasingly gained attention in the energy industry. sCO₂ power cycles has various advantages, such as high cycle efficiency, compact turbomachinery, and potential zero CO₂ emission. Along with these benefits, materials degradation issues have also been emphasized in the last decade. Aqueous...
