Abstract
Domain boundaries on (001), (111) and (112) planes in the μ phase of a superalloy were found by high resolution electron microscopy. These boundaries consisted of the following tetrahedrally close-packed phases: (001), other stacking variants such as C14, C15, C36, K7Cs6- and Zr4Al3-types; (111), C14, C (V2(Co, Si)3-type); and (112), differently oriented μ W2FeSi-type, M. The intergrowth of these closely related phases with pentagonal antiprisms excludes any disorder at these boundaries.Keywords
