Grooving of a grain boundary by evaporation–condensation below the roughening transition
grain boundary evaporation–condensation below roughening transition
2015/10/16
The development of surface grooves at grain boundaries that intersect a planar surface is analyzed for the case that the evolution occurs below the thermodynamic roughening transition by evaporation–c...
The effects of boron impurity atoms on nickel Σ 5 (012) grain boundary by first principles calculations
Ab-initio calculation Stress corrosion cracking Tensile test

Response to Comments on Paper on Grain Boundary Scattering Model for Metals
Grain Boundary Scattering Model Metals
2010/12/28
The electrical conductivity of a polycrystalline metal film has been studied for a model in which the background scattering and grain boundary scattering are independent. The external surface electron...
