  • An Experimental and Numerical Investigation of Tall Mechanically Stabilized Earth Walls

    Creator:
    Strahler, Andrew W.
    Abstract:
    The implementation and construction of Mechanically Stabilized Earth (MSE) walls has undergone substantial expansions in recent years, owing to its relatively low cost, ease of construction, and high efficiency compared to conventional retaining methods. As a result, MSE walls are being constructed to greater heights with complex features (e.g. multiple...

  • Structure-property relationships of layered oxypnictides

    Creator:
    Muir, Sean W.
    Abstract:
    Investigating the structure-property relationships of solid state materials can help improve many of the materials we use each day in life. It can also lead to the discovery of materials with interesting and unforeseen properties. In this work the structure property relationships of newly discovered layered oxypnictide phases are presented...

  • Structure-Property Relationships of Disordered Electronic Materials : From Crystalline to Amorphous

    Creator:
    Surta, Todd Wesley, Jr.
    Abstract:
    Two perovskite materials (Bi0.5(A)0.5)(Sc0.5Nb0.5)O3, where A = K+ and Na+ were synthesized phase pure for the first time. Their structures were determined by indexing synchrotron X-ray diffraction data and subsequent combined Rietveld refinement on neutron and synchrotron X-ray diffraction data revealing significant disorder on the A-sites of these materials. A...

  • Characterization of Heterostructured Nanocrystalline Metals Processed by High-Pressure Torsion

    Creator:
    Han, Jae-Kyung
    Abstract:
    High-pressure torsion (HPT) is an effective severe plastic deformation (SPD) technique to produce bulk nanostructured materials (BNMs). These BNMs often show a combination of exceptional mechanical and physical properties. Processing of single metals and alloys by HPT has been understood that the homogenous microstructures can be achieved throughout the disk...

  • Development of Temperature Stable Dielectric Materials Based on Lead Bismuth Perovskite Solid Solutions

    Creator:
    Colton, Zachary D.
    Abstract:
    High energy density ceramic capacitors with temperature stable permittivity across -150°C to 300°C are desired for a wide variety of electronic devices. Traditional dielectrics such as barium titanate provide a high permittivity but that permittivity is strongly temperature dependent over this specified temperature range. The goal of this work is...
