The main phases in the structures of composites of cBN???Al and cBN???Al???TiB??? systems, obtained by reaction sintering under high pressure, were studied by X-ray analysis specifying the fill factor of correct positions of atoms in crystal lattices. Analysis of two models of the boron atoms placement in the crystal lattice of AlN-wurtzite has shown ...

The experimentally-rated method of modeling of porous and grain structures of cubic boron nitride composites, which obtain by reactionary sintering with preimpregnation by aluminium under pressure is proposed. Possibility of process control of aluminium dispersing in a mixture at an impregnation stage under pressure is shown.
