The grain boundary free surface triple line tension and grain boundary triple line tension were investigated in copper using a recently introduced novel approach. The effect of triple line tension on grain growth, Zener drag and Gibbs-Thompson relation was studied. The results showed that the triple line tension has a considerable effect on grain growth, particle boundary interactions and void shape, especially for nanocrystalline materials.
