Abstract

The structure of triple junctions of large-angle inclined boundaries 〈111〉 and 〈100〉 and mixed grain boundaries in nickel is investigated by a molecular-dynamic method. The equilibrium triple junction has no structural features that would identify it as a special defect against the background of the corresponding grain boundaries. The effective radius of the triple junctions and the width of the grain boundaries are determined.
