Abstract

Graphical abstract: Abstract: A simple and efficient method for grain growth simulation is presented to account for the existence of free surfaces in polycrystalline solids. This method extends a phase-field model of grain growth, controlling the enthalpy and mean temperature of the system to maintain macroscopic shape of specimens. Effects of free surfaces and specimen shapes on the evolution of grain structure and the shape of individual grains in polycrystalline sheets and rods are examined.
