Abstract

The effect of heat-treatment on precipitate morphology has been studied by transmission electron microscopy. In this study, a thin-film sample was prepared from bulk material in which spinel (NiFe2O4) particles had been precipitated within a NiO matrix. Individual precipitates were then characterized by dark-field imaging in the electron microscope between a series of annealing treatments. These coherent precipitates transform from dendrites, which have "arms" in the 〈001〉 directions bounded by {111} and {011} planes, to octahedra bounded by {111} planes. In addition, smaller precipitates have also been observed to shrink and even disappear between a series of anneals. © 1989.
