  • Characterization of TiNbHf alloys for potential medical dental applications

    Creator:
    Amick, Darryl D.
    Abstract:
    A series of TiNbHf alloys ranging from 0-40 atomic % Nb and 0-15 atomic % Hf were evaluated to investigate low-elastic modulus phenomena which occur in this ternary system. The desirability of utilizing corrosion-resistant, biocompatible alloys with elastic modulus values approaching that of human bone for medical prosthetic implants provides...

  • Application of Titanium Alloy Bars for Strengthening Reinforced Concrete Bridge Girders in Flexure

    Creator:
    Vavra, Eric
    Abstract:
    Structurally efficient and cost-effective solutions are needed to extend the service-life of deficient and aging highway infrastructure around the world. One critical need is to increase the flexural strength of older reinforced concrete (RC) structures to carry heavier and more frequent loads. Titanium alloy bars (TiAB) offer a new opportunity...

  • Shear strengthening reinforced concrete bridge girders using near-surface mounted titanium alloy bars

    Creator:
    Knudtsen, Jonathan
    Abstract:
    Aging and deficient infrastructure has become a major problem throughout the world. This is particularly evident in the case of reinforced concrete (RC) bridges. The cost of replacing these bridges is often prohibitive, thus engineers must find ways to strengthen them. Many older RC bridges predate the modern understanding of...

  • Seismic Performance of Square Reinforced Concrete Columns Retrofitted with Titanium Alloy Bars

    Creator:
    Lostra, Mackenzie M. W.
    Abstract:
    Large numbers of reinforced concrete (RC) bridges were built in the past that are now considered seismically deficient. The structural members most likely to be considered deficient are the supporting columns. Typical deficient columns contain inadequate transverse reinforcement and poorly detailed lap splice lengths above the foundation. Insufficient lap splice...
