Abstract
The microstructure of an internally oxidized CuMg alloy has been examined b y means of high-resolution transmission electron microscopy. A new orientat ional. relationship, Sigma 21 [211], has been determined by selected-area e lectron diffraction. The dislocation network for such an orientational. rel ationship, calculated using the near coincident site lattice theory, is a p arallel array of edge dislocations with Burgers vectors of the type 1/21[l 0 2 (1) over bar], 1/21[1 (4) over bar 2], and 1/21[(4) over bar (5) over b ar (8) over bar].
