Notes:
The theoretical crystal morphology of the Al3Ni intermetallic compound has been deduced from energy calculations. 14 directions of atomic periodic bond chains have been defined, using the Hartman method, from which 11 facet orientations have been determined. For each of them a computer simulation has given the relative potential energy of the atoms at the different sites on the surface, the corresponding energy of fixing and hence the attachment order of the atoms. The theoretical morphology of Al3Ni is shown to be made from planes {110}, {101}, {111}, {020} and {002}. The first four plane directions have been observed on dendrites and massive crystals.
