Wetting of Copper Nanoparticles on Copper 110 Surface with EAM

This page shows visualizations the FCC Cu lattice using EAM potentials derived by M.I. Mendelev and A.H. King through LAMMPS and OVITO with resources from the University of Tennessee

My research focuses on GRCop-84 which was developed specifically for combustion chamber liners, is best available material for it), and represents a rare case where Additive Manufacturing (AM) is the best tool for fabrication. It's microstructure is fairly simple, composed primarily (86 vol %) of an FCC Cu matrix, but it is unique in a number of ways. This alloy is made with Powder Bed Fusion a form of AM where metal powder is spread over a surface and melted with a high powered laser directly. The simulation shown here is an attempt to simulate the melting of nano-particles to an ordered surface with EAM and NvT. The temperature of the sphere and wall are controlled separately, though in this particular case, the sphere and wall initial temperatures were set to 1200 K each and equilibrated to 800 K.
