Investigation of phase competition in the Ni-Al system at the early stages of nucleation
Main Article Content
Abstract
The paper presents a computer model to test the hypothesis of the possibility of a metastable contact melting using the CALPHAD approach. Сurves of the Gibbs energy versus nickel concentration were constructed. Based on the assumption that in the early stages of nucleation a kinetic suppression of stable intermetallic phases is possible, the metastable phase diagram is constructed. The kinetics of growth of the liquid layer of nickel-aluminum solution is investigated.
