3D periodic arrangement of misfitting precipitates in anisotropic materials

In high temperature applications Nickel-base alloys are frequently used. Th ese two-phase materials consist of misfitting precipitates, which are perio dically arranged in the matrix material. The physical behaviour of such mat erials strongly depends on the morphology and on the volume fraction of the inclusions. The interfacial energy and the elastic strain energy are utili zed in the determination of equilibrium shapes, incorporating the concept o f generalized driving forces. as an efficient numerical method the Boundary Element Method for anisotropic materials is used. Results are presented fo r cubic materials to mimic Ni-base alloys. The influence of volume fraction , particle size, elastic inhomogeneity and external loading on the equilibr ium morphology is discussed.
