Determination of the two-melt phase boundary and study of the binary diffusion in liquid Bi–Ga system with a miscibility gap

Temperature-Induced Liquid-Liquid Transition in Metallic Melts: A Brief Review on the New Physical Phenomenon

“…By neutron diffraction and small-angle neutron scattering, a collaborative study on molten Al-Si alloys were carried out by University of Rouen (France), Ames Laboratory and Oak Ridge National Laboratory, and the results unambiguously show that for the eutectic Al-Si melt, the microstructure changes with increasing temperature in a partly reversible way, while for the hypereutectic (Al-Si20at%) melt, the change is almost completely irreversible [57]. A similar case was also found in a liquid Bi-Ga System [58]. Also, with the temperature dependence of the density, the viscosity and other properties of the Pd-18 at.% Si melt measured, Sivkov (Russia) et al observed the existence of micro heterogeneities in the melt and a transformation of its microstructure at 1380-1430 K during a temperature cycle of heating and cooling [59].…”

Investigation of microheterogeneities in Ga–Pb melts by acoustic methods

“…The difference between the lead concentration close to the bottom and the upper edge of a sample is obviously largest when the melt composition is close to the critical one. The profiles obtained in our work for melts with 40 and 50 at.% Pb are in a good agreement with ones at critical concentration near T S as shown in [8].…”

Liquid–Liquid Coexistence Curve of n-Perfluorohexane–n-Hexane System

“…The law of radiation attenuation in a binary mixture with components A and B may be written as [3,4] …”

“…In this article are presented new data for the liquidliquid phase boundary of the C 6 F 14 -C 6 H 14 system, obtained by the γ -ray attenuation technique. The authors previously used this method to explore a number of binary liquid metal systems with a miscibility gap [3,4], and these measurements established its reliability. …”
