    Atomistic characterization of stochastic cavitation of a binary metallic liquid under negative pressure 

    An, Qi; Garrett, Glenn; Samwer, Konrad; Liu, Yi; Zybin, Sergey V.; Luo, Sheng-Nian; Demetriou, Marios D.; Johnson, William L.; Goddard III, William A. (American Chemical Society, 2011)
    We demonstrate the stochastic nature of cavitation in a binary metallic liquid Cu46Zr54 during hydrostatic expansion by employing molecular dynamics (MD) simulations using a quantum mechanics (QM)-derived potential. The ...

    How the toughness in metallic glasses depends on topological and chemical heterogeneity 

    An, Qi; Samwer, Konrad; Demetriou, Marios D.; Floyd, Michael C.; Duggins, Danielle O.; Johnson, William L.; Goddard III, William A. (National Academy of Sciences, 2016)
    To gain insight into the large toughness variability observed between metallic glasses (MGs), we examine the origin of fracture toughness through bending experiments and molecular dynamics (MD) simulations for two binary ...

    Predicted optimum composition for the glass-forming ability of bulk amorphous alloys: Application to Cu–Zr–Al 

    An, Qi; Samwer, Konrad; Goddard III, William A.; Johnson, William L.; Jaramillo-Botero, Andres; Garrett, Glenn; Demetriou, Marios D. (American Chemical Society, 2012)
    Metallic glasses have been established to have unique properties such as ductility, toughness, and soft magnetism with promising engineering applications. However, the glass-forming ability (GFA) has not been sufficient ...
