The energy dependence of the {111} and {100} tilt grain boundaries on disorientation angle in Ni3Al

摘要

Dependence of the energy of {111} and {100} boundaries on tilt angle θ is investigated by the molecular dynamics method using intermetallic Ni3Al as an example. It is shown that the energy (per single grain dislocation) of grain boundaries in the {111} planes is higher than that of the grains located in the {100} planes.
