Non-planar dislocation dissociations and cores play a fundamental role in mechanical properties of many materials. In this contribution, we concentrate on the complex structures arising from a large number of possible metastable stacking faults in disilicides with the C11(b) structure, specifically MoSi2. First, gamma-surfaces for the planes with high atomic density in this intermetallic are presented. Employing these results, possible configurations of dislocation dissociations are discussed and related to the deformation behavior.
