Abstract
The structure of the interfaces between a f.c.c. matrix and b.c.c. pre cipitates, across which a Kurdjumov-Sachs orientation relationship hol ds, was examined in a Ni-45 mass% Cr alloy. Intruder matrix dislocatio ns, whose Burgers vector is not parallel to the(111)(f.c.c.)//(110)(b. c.c.) interface, were found to create new growth ledges. These disloca tions can accommodate the misfit between the interplanar spacings of c lose-packed planes parallel to each other.
