On the dependence of the phase diagram of a substitutional alloy on size and shape of a nanocrystal
Institute for Geothermal Research of the Dagestan Scientific Center of RAS
Abstract: A method for calculating of solidus and liquidus temperatures for a disordered substitutional alloy is proposed. The method was tested on the SiGe alloy and it was obtained a good agreement with experimental data. It is shown that when the size of a nanocrystal of the solid substitution solution decreases, the difference between the liquidus and solidus temperatures decreases the more, the more noticeably of the nanocrystal shape is deflected from the most energetically optimal shape.
Keywords: substitution alloy, temperatures of solidus and liquidus, nanocrystal.
