Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

Creator:: Bowen, Michael S.
Abstract:: Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

The Effect of Isothermal Aging on the Development of Long-Range Order in Ni-based Alloys

Creator:: Aerne, Nicholas S. J.
Abstract:: Nickel (Ni)-based alloys with a high chromium (Cr) content are frequently employed in applications where elevated temperatures and/or corrosive environments are present due to their excellent corrosion resistance and mechanical properties. However, a gap exists around the formation, and kinetics of long-range order (LRO) Ni2Cr phase in both model binary...

Heat Treatment Effects on the Mechanical Properties and Microstructure of CPM-M4 Tool Steel

Creator:: Fast, Cody P.
Abstract:: Variations in heat treatments have significant effects on the microstructure of tool steels. For CPM-M4 tool steel, the changes in microstructure and mechanical properties were observed based off of variations in temperature. Five heat treatments with constant exposure time and variable austenitizing and tempering temperatures were performed on samples of...

High Temperature Electrical Properties of Ceria-Based Ceramics for Use as Electrodes in Magnetohydrodynamic Power Generators

Creator:: Bowen, Michael S.
Abstract:: Determining the electrical properties of ceria-based materials is important for their use as electrodes in hot-wall magnetohydrodynamic (MHD) power generators with wall temperatures greater than 1500 ̊C. The electrical conductivity of a material can be used in models for predicting the performance of generator designs. More specifically, the temperature dependent...

Sampling submicrometer particles suspended in near sonic and supersonic free jets of air

Creator:: Martone, Joseph Arthur
Abstract:: This experiment is concerned with sampling submicrometer particles in near sonic and supersonic flows. The study employed a high volume condensation aerosol generator to produce stearic acid particles having a geometric mean diameter of 0.8 μm and a geometric standard deviation of 1.28. The aerosol was diluted with dry air...

Distortion-induced fatigue cracking of girder-to-crossbeam connection

Creator:: Aljutaili, Dhari S.
Abstract:: Oregon Department of Transportation’s bridge no. 9743b is a multi-span, two-girder steel deck bridge connecting the busy interstates 5 and 205. Vertical cracks have been detected in the welded girder-to-crossbeam connections at the bents. Distortion-induced fatigue is suspected to be responsible for the cracking. Linear elastic beam analysis, 2-D and...
