Long – Time relaxation in liquid eutectics
For binary systems with eutectic equilibrium, the existence of liquid – liquid critical point in the solid – liquid two-phase area is established. The width of corresponding fluctuation region is estimated by Ginsburg-Levanyuk criterion, and it is shown to constitute up to several hundred degrees. T...

Summary: | For binary systems with eutectic equilibrium, the existence of liquid – liquid critical point in the solid – liquid two-phase area is established. The width of corresponding fluctuation region is estimated by Ginsburg-Levanyuk criterion, and it is shown to constitute up to several hundred degrees. Thus, in that wide region, the system should be described in terms of critical dynamics, which implies the critical slowing – down and non-monotonic relaxation.
•For eutectics, the existence of critical points in metastable liquid is established.•The fluctuation area is estimated by Ginsburg – Levanyuk criterion.•It is shown to constitute up to several hundred degrees.•In the fluctuation area, the critical slowing – down and nonmonotonic relaxation occur.•Al-Y binary system is the example of such complicated relaxation behaviour. |
