Grain Size-Dependent Thermal Expansion of Nanocrystalline Metals

Grain Size-Dependent Thermal Expansion of Nanocrystalline Metals

In the present work, we have used classical molecular dynamics and quantum mechanical density functional theory modeling to investigate the grain size-dependent thermal expansion coefficient (CTE) of nanocrystalline Cu. We find that the CTE increases by up to 20% with a gradually decreasing grain si...
