Atomistic simulations of the structures of Pd-Pt bimetallic nanoparticles and nanowires
Kayoung Yun, Pil-Ryung Cha, Jaegab Lee +2
Bimetallic nanoalloys such as nanoparticles and nanowires are attracting significant attention due to their vast potential applications such as in catalysis and nanoelectronics. No…
Monte Carlo simulations of the structure of Pt-based bimetallic nanoparticles
Kayoung Yun, Yong-Hun Cho, Pil-Ryung Cha +5
Pt-based bimetallic nanoparticles have attracted significant attention as a promising replacement for expensive Pt nanoparticles. In the systematic design of bimetallic nanoparticl…
Molecular dynamics simulation of Ga penetration along Al grain boundaries under a constant strain rate condition
Ho-Seok Nam, David J. Srolovitz
While diverse fracture characteristics have been observed in liquid metal embrittlement (LME) depending on the solid-liquid metal pairs, the penetration of nanometer-thick liquid m…
Molecular Dynamics Simulation of Ga Penetration along Sigma 5 Symmetric Tilt Grain Boundaries in an Al Bicrystal
Ho-Seok Nam, David J. Srolovitz
Liquid metal embrittlement (LME) is a common feature of systems in which a low melting point liquid metal is in contact with another, higher melting point, polycrystalline metal. W…
Molecular Dynamics Simulation of Ga Penetration along Grain Boundaries in Al: a Dislocation Climb Mechanism
Ho-Seok Nam, D. J. Srolovitz
Many systems where a liquid metal is in contact with a polycrystalline solid exhibit deep liquid grooves where the grain boundary meets the solid-liquid interface. For example, liq…
Solid-Liquid Phase Diagrams for Binary Metallic Alloys: Adjustable Interatomic Potentials
H. -S. Nam, M. I. Mendelev, D. J. Srolovitz
We develop a new approach to determining LJ-EAM potentials for alloys and use these to determine the solid-liquid phase diagrams for binary metallic alloys using Kofke's Gibbs-Duhe…
