Spontaneous amorphization of high-pressure phases in binary alloys of B-elements

Common factors are analyzed for a special case of alloy amorphisation in binary systems of B-elements (s, p-elements of IIB-VB subgroups of the periodic table) after high pressure action. The alloys having a semiconductor phase in the initial state change under pressure to a new crystal state-a high-pressure metal phase, which is retained by quenching down to low temperature at atmospheric pressure. With increasing temperature the quenched phase loses stability and the alloy becomes amorphous. There exists a range of alloy compositions favourable for amorphization, corresponding to a electron concentration of 3.7 to 4.0 electrons per atom. [Russian Text Ignored].
