| Summary: | Заглавие с титульного экрана Influence of the hydrogen and boron segregation on the grain boundary cohesion in iron with asymmetric grain boundary Σ5(310) was investigated by the projector augmented-wave method within the densityfunctional theory. The binding energies for H and B at the grain boundary and on the free surface werecalculated. It was found that hydrogen prefers to be bonded on the Fe surface while the highest binding energy ofboron was found at the grain boundary. It was shown that hydrogen leads to deteriorate cohesive properties ofFe whereas boron results to improvement grain boundary cohesion. |
