Understanding the interactions of Σ3n boundaries and the triple junction character is important in the context of grain boundary engineering in cubic materials. In a triple junction, when two boundaries are Σ3 and Σ9, the third boundary is either a Σ3 or a Σ27 as per the Σ-combination rule. In the present work, the role of the misorientation axis of the interacting Σ boundaries on the character of the third boundary is systematically studied. The calculated probabilities of occurrences of Σ3, Σ9 and Σ27 boundaries are correlated with the experimental triple junction distributions in Ni and Ni based superalloys. © 2019 Elsevier Inc.
