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...

Aqueous Corrosion and High Temperature Oxidation in Supercritical Carbon Dioxide Environments

Creator:: Teeter, Lucas
Abstract:: The corrosion resistance of steels and nickel based alloys was investigated in supercritical CO2 (sCO2). Two types of experiments were conducted. The first set of experiments were conducted in a low temperature aqueous environment to simulate conditions that would exist in direct sCO2 power cycle low temperature heat exchangers. The...

Characterization and Development of Ni-based Superalloys for Supercritical Carbon Dioxide Applications

Creator:: Adam, Benjamin M.
Abstract:: The advent of supercritical CO2 as a new heat-exchange medium has seen strong interest from the power industry and the energy research field recently. It is advan- tageous in comparison with other heat-exchange cycles, as it can be operated safely at much higher temperatures and pressures, thus increasing the thermal...

Investigation of Thermal Degradation in Structural Alloys for Nuclear Power Systems

Creator:: Teng, Fei
Abstract:: The thermal degradation of structural materials is considered to be a key factor for evaluating the lifetime of current nuclear power plants. Ni-based and Fe-based alloys, such as 690, 625, 304, and 316, are widely used in nuclear industry as structural components due to the extraordinary corrosion resistance and mechanical...

Adaptive Learning Module for Introduction to Materials Science

Creator:: Nigon, Nutnicha
Abstract:: There is a growing need for individualized instructional designs in 4-year institutions due to: 1) growing undergraduate enrollment trends across the U.S., 2) broader diversity in students backgrounds, and 3) the growing prevalence of asynchronous remote learning. With the growth in computer technology in education, tools such as adaptive intelligent...

Wholistic primary education : investigation and development of an integrated curriculum model

Creator:: Beyer, Elmira K.
Abstract:: A five year longitudinal study was begun in 1976 to find a solution to the problem of early primary children who fail in school and then adopt the failure syndrome. The study was conducted in four elementary schools in Oregon which had distinctly different socio-economic populations. The tests used for...

A study of the mathematical competence requirements for graduation among Oregon's A-AA-AAA senior high schools

Creator:: MacFarlane, William Henry
Abstract:: Competency-based education was introduced to the state of Oregon in the early 1970's, mandating that the graduating classes of 1978 would meet these competency requirements for graduation. The Oregon Department of Education allowed each school district to compile its own lists of competencies in each of the mandated areas. There...

Numerical classification of range vegetation and statistical analysis of its ecology

Creator:: Pyott, William Tucker, 1936-
Abstract:: The purpose of the research was to computerize mathematical procedures for the analysis of range vegetation and environmental data. The specific objectives were as follows: 1. to develop and apply computer techniques to the classification of vegetation in order to provide a phytosociological framework within which to investigate the ecology...
