摘要：

Atomic structure and energy of triple junctions of <111> and <100> tilt boundaries in nickel were studied by the method of molecular dynamics. It is shown that the formation energy of equilibrium triple junctions of tilt boundaries as a special defect is practically zero, and a triple junction is, in fact, a part of its constituent grain boundaries. It is noted that in the center of a triple junction of low-angle tilt boundaries a defect-free region is often formed.
