摘要：

The diffusion permeability of triple junctions of high-angle tilt boundaries aOE (c) 111 > and aOE (c) 100 > and mixed-type boundaries in nickel has been investigated using the molecular dynamics method. It has been shown that the diffusion permeability of equilibrium triple junctions does not exceed the permeability of the grain boundaries forming them. The effective diffusion radius of the considered triple junctions and the width of the grain boundaries are determined.
