Abstract
This paper assesses the contribution of grain boundary triple junctions to the driving force for grain growth and the “energetic” effect of boundary junctions on grain growth in nanocrystalline materials. The first measurement of grain boundary line tension allows the quantitative estimation of the fraction of the driving force due to boundary triple junctions. For polycrystals with a grain size in the range ∼50 nm, it is comparable with the driving force from grain boundaries.
