  • The role of thermal spike Compactness in radiation-induced disordering and Frenkel pair production in Ni3Al
    Scripta Materialia, 2012
    Co-Authors: S. A. Skirlo, Michael J. Demkowicz
    Abstract:

    We show that the shape of the kinetic energy distribution in radiation-induced thermal spikes may be described using a dimensionless number, proportional to (volume) 2/3 /(surface area), known as Compactness. The disorder produced in thermal spikes in Ni 3 Al increases with Compactness because the thermal spike cooling rate, which determines the time available for thermal disordering, decreases with Compactness. On the other hand, Frenkel pair production is inversely correlated to Compactness because longer thermal spike lifetimes enhance vacancy–interstitial recombination.

    Co-Authors: S. A. Skirlo, Michael J. Demkowicz
    Abstract:

    We show that the shape of the kinetic energy distribution in radiation-induced thermal spikes may be described using a dimensionless number, proportional to (volume)[superscript 2/3]/(surface area), known as Compactness. The disorder produced in thermal spikes in Ni[subscript 3]Al increases with Compactness because the thermal spike cooling rate, which determines the time available for thermal disordering, decreases with Compactness. On the other hand, Frenkel pair production is inversely correlated to Compactness because longer thermal spike lifetimes enhance vacancy–interstitial recombination
