Abstract
The crystallography of some lesser known stacking faults within a martensite variant in a Cu-Zn-Al alloy has been analysed. The faults have been found to lie on the ([MATH]28) planes of the β'1 martensite, that are different from the ([MATH]8) twinning planes separating specific self-accommodating variants. The defects have also been found to appear in combination with faults on the basal plane, forming a domain-like configuration. The relevance of these ([MATH]28) planes is discussed in relation to the correspondance between parent β and martensite lattices.
