    Two-phase microstructure of orderer cube-shaped precipitates in the disorderer matrix is characteristic of Ni-base superalloys. This microstructure degrades under the applied stress:depending on the stress direction, latice misfit and elastic parameters of both constituent phases, the precipitates coalesce and change their overall shape. Various atomic configurations were modeled in this work representing various morphologies of precipitates developed under applied stress. A model Ni-base alloy containing six alloing elements typical of advanced Ni-besed superalloys was used. Generated configurations were further subject to study of elastic parameters by means of computer straining experiments.
