Abstract
The microstructure and morphology of directionally solidified samples of the pseudobinary eutectic alloy CoNi-Cr23C6 have been characterized with respect to the growth rate and temperature gradient. Transmission electron microscopy studies show that, in spite of the irregularity of the microstructure, a simple and reproducible cube-cube orientation relationship exists between the phases, which can be explained in terms of the close atomic coincidence between the crystal lattices. The observed microstructures can readily be related to the crystallographic preferred growth directions of the alloy.
