  • Role of Stoichiometry on Ordering in Ni-Cr Alloys

    Creator:
    Teng, Fei
    Abstract:
    Mechanical property degradation due to isothermal ageing is of potential concern for alloys based on the Ni-Cr binary system (e.g., Inconel 690, 625), particularly in nuclear power applications where component lifetimes can exceed 40 years. In the present research, the disorder-order phase transformation, which is the primary mechanism of ageing,...

  • Influence of processing parameters on diffusion of divalent nickel in wet silica sol-gel monoliths

    Creator:
    Dickson, David J.
    Abstract:
    The diffusion of divalent nickel (Ni²⁺) from wet silica gels was investigated. Silica gel is gaining interest as an encapsulation matrix for biological components. The transport of biologically relevant species within the gel is determined by the structural characteristics of the gel, which are in turn governed by synthesis parameters....

  • Characterization of high temperature fatigue mechanisms in Haynes 282 nickel based superalloy

    Creator:
    Rozman, Kyle A.
    Abstract:
    Electric power needs will only grow over the next decades as more humans ascend from poverty into the middle class. Currently, the majority of electric power is generated by burning fossil fuels. To help mitigate the undesirable effects of burning fossil fuels research is being done to increase the efficiency...
