  • Exploring the Ductility Minimum of Niobium C103 at Intermediate Temperatures using Triaxial Tensile Specimens

    Creator:
    Wood, Thomas N., II
    Abstract:
    This work explores the mechanical properties of single-phase niobium alloy C103 from room temperature to 600°C for the purpose of expanding safe uses of the material into new applications. The study utilizes a symmetrically notched triaxial tensile specimens to manipulate the internal stress field in order to observe the changes...

  • The Processing and Microstructures of 309L Stainless Steel Clad onto Carbon Steel with Wire-fed Directed Energy Deposition

    Creator:
    Bozeman, Scott C.
    Abstract:
    Directed energy deposition and laser cladding technologies are suitable advanced manufacturing techniques for applying corrosion-resistant claddings to large carbon steel components. In this work, we clad 309L stainless steel wire onto carbon steel substrates and examine the effects of cladding parameters (laser power and travel speed) on metallurgical bonding, composition,...

  • 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...

  • 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...

  • 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...

  • Acceleration of Long-Range Ordering in NiCrFe Alloys Via Proton Irradiation

    Creator:
    Evered, Cole E.
    Abstract:
    This work explores the hypothesis that proton irradiation is a feasible alternative to simulate accelerated thermal aging for Ni2Cr long-range ordered phase formation within NiCr and NiCrFe alloys. In this study, various model alloys and commercial alloys 690 and 690+P (0.01 wt.% P) were subject to 2 MeV proton irradiation...

  • Impact of Hot Isostatic Pressing Parameters on Interface Evolution in Uranium Molybdenum Monolithic Plate Fuel

    Creator:
    Koziol, Adam
    Abstract:
    The monolithic (plate type) Uranium 10 wt.\% Molybdenum (U-10Mo) fuel system is promising for a variety of applications, most notably for the replacement of highly enriched uranium (HEU) fuels with low enriched uranium (LEU) fuel in United State High Performance Research Reactors (U.S. HPRRs). Phase transformations and secondary phase formation...

  • Time-Dependent Crack Growth Mechanisms in Alloy 617 at 800°C in Air

    Creator:
    Addison, Dylan, A.
    Abstract:
    Time-dependent crack growth mechanisms in Alloy 617 at 800°C in air were studied using compact tension samples machined in the L-T direction, cracked at temperature using an induction furnace and servo-hydraulic load frame. The application of different loading waveforms, including triangular, hold time, and sustained loading, were studied with relation...

  • 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...
