Crystallograhic textures of phases in eutectics AO + ZrO (Y203) were investigated by means of X-ray diffraction. In all studied eutectic polycrystalls (grown from the melt by EFG technique) a preferred orientation [0001] of A1203 along the growth direction in all the samples was revealed for both initial orientations of A120 seeding crystal: <0001> and <1011>. For a cubic ZrO there were two types of a preferred orientations: sharp ones, close to <123> with a 6-fold symmetry and more spread <110>. Such a 6-fold symmetry for a cubic phase appears in eutectic due to a joint crystallization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
