Intracrystallite Liquation in Ternary Alloys-Solid Solutions

摘要

The nonequilibrium crystallization in ternary alloys-solid solutions of the A-B-C model system and actual Cu-Ni-Mn system-are calculated according to the Petrov-Scheil model. It is shown that the temperature at which the distribution coefficient of the medium-melting component is 1 and the temperature at which the content of this component in the isolated solid phase is maximal are different for intracrystallite liquation in both cases. The conditions are formulated under which the parameters of the intracrystallite liquation should be compared with the characteristics of the dendritic liquation.
