MgNi2 and MgCu0.4Zn1.6, two C36 Laves phases, were plastically deformed at elevated temperatures, and, the deformation-induced defects were studied by TEM. Extensive faulting was observed, consistent with the low stacking-fault energy of the C36 structure. HREM revealed multi-layer faults with a variety of stacking sequences.
