SYSTEMATICS AND ANALYSIS OF PLANAR SUPER-STRUCTURAL DEFECTS IN ORDERED ALLOYS ON BASE OF HEXAGONAL DENSE PACKING

The investigation objects are the ordered alloys on base of the hexagonal dense packing (HDP). On base of solving crystallometric problems (addition of non-lattice packing by the units unoccupied with the atoms, up to the lattice, specification of connection between different procedures of describing cell of the crystal periodicity and a number of other ones) the systematics of the planar-structural defects (PSD) in the free ordered alloy on base of HDP has been performed. The methods of obtaining analytical expression of the PSD energy in the alloys on base of HDP in the model of the solid spheres without limitation to the number of the coorinated spheres taken in interaction of the atoms into consideration have been proposed. The phenomenological description of the energy spectrum for formation of the conservative and non-conservative type AFG relatively to the super-structure has been performed. The computer program for personal computers permitting to analyse the planar defects in HDP of the alloys has been developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
