Molecular Dynamics Simulations on Nanocomposites Formed by Intermetallic Dispersoids of B2 Structure and Aluminum Matrices

Namkung M., Paik S., Wincheski R.A., NASA Langley Rsearch Center, US

Molecular dynamics simulations were performed in order to characterize the local lattice structure in the vicinity of the interfaces between nanosized B2 intermetallic aluminide dispersoids and aluminum matrices. The dispersoid materials selected for the present [...]

Molecular Dynamics Simulation on Characteristics of Nano-sized Nickel Aluminide Dispersoids in Aluminum Matrix

Namkung M., Paik S., Wincheski R.A., NASA Langley Research Center, US

Molecular dynamics simulations were performed on the morphology of the interfaces between intermetallic nano-sized dispersoids of Ni3Al and NiAl, and a pure aluminum matrix. The lattice constants of dispersoids were initially set to be identical [...]

Thermodynamic Behaviors of Nano-Sized Au Clusters on the (001) Surface

Namkung M., Wincheski R.A., NASA Langley Research Center, US

We have studied thermal expansion of the surface layers of the hexagonally reconstructed Au (001) surface using a classical Molecular Dynamics (MD) simulation technique with an Embedded Atomic Method (EAM) type many-body potential. We find [...]
