Stability phase was analyzed in terms of energy education. It was found that c-Mg4C8B48 phase is the most stable in particular in connection with the formation of stable С-B4 clusters. The atomic configuration, density, electron and phonon states of the materials you study by comparison. Structural similarity functions for amorphous boron BAM materials indicates that boron forms a very similar amorphous network in different structures. BAM amorphous network structure represents fragments of the B-B disorder in the network. The structure consists of amorphous boron icosahedral fragments and bioktaedriv joined the amorphous matrix. Calculated phonon spectra of crystalline Al4Mg4B56 Al3Mg3B56 and Al4Li4B56 quite good agreement with the Raman spectrum. For boron BAM structures, the strengthening of inter-icosahedral bonds after amorphization leads to increased fluctuations in the range of 1100-1250 cm-1 It was explained by the anisotropy of the great tensile strength and a shift in terms of the layered framework of clusters B12 in amorphous materials ioru and BAM. Increasing the strength of amorphous films, due to the compressive stress and the presence of oxygen. These factors contribute to the formation of the icosahedral clusters.
