Molecular Dynamics Study On The Grain Growth In Nanocrystalline Aluminum, Jielong Yin Jun 2016

Molecular Dynamics Study On The Grain Growth In Nanocrystalline Aluminum, Jielong Yin

Mechanical Engineering Master's Theses

In recent years, nano-materials have been a popular direction of research in the field of materials science. Nanocrystalline aluminum has been of particular intrest among the nano-materials. This thesis describes the results of three-dimensional molecular dynamics simulations that have been performed to study grain growth in nanocrystalline FCC aluminum. This project built the models by using the Voronoi geometry method to study the grain growth mechanism, grain boundary structure and the effects of temperature and grain size on the crystal structure and grain growth by Energy Analysis, Radial Distribution Function (RDF) analysis, and investigating changes in Centro symmetric parameters.
