“…This assumption is supported by the results reported in [38,39], where conductivity of Cu-REM (Ce, Eu, Gd) melts was studied in the range 1200-1500 K. These studies established that higher REM content of copper alloys led to a sharp increase in resistivity at x Gd = 0.4. The increase in resistivity is evidence of lower concentration of charge carriers, which may be primarily associated with electron localization when short-range ordering like a chemical compound is established in the melts.…”

The composition and temperature dependences of thermodynamic functions of mixing in liquid alloys of copper with rare-earth metals and their variation in the series are considered. It is shown for majority of systems in the series that the most intensive interaction between components is observed in the composition range enriched with copper. The negative deviations of thermodynamic properties of mixing increase with decreasing temperature. The main features of the temperaturecomposition dependence are explained under the assumption that chemical short-range ordering like a chemical compound forms in the Cu-REM liquid alloys. The temperature-composition dependence of thermodynamic functions of mixing is described in the framework of the ideal associated solution model.

“…Over the past decades, much attention has been paid to the research of liquid-liquid structure transition (L-LST) and resistivity of liquids. [6][7][8][9][10][11] Considerable investigations reveal or indicate the existence of the L-LSTs with reversible or irreversible characters in many liquid metals and alloys. [12][13][14][15][16] Many researchers focus on the microstructure and properties of lead-free solder; however, little attention has been paid to the liquid properties of lead-free solder.…”

2015): Effect of Ce on resistivity of Sn-3.8Ag-0.7Cu-xCe lead-free solders, Physics and Chemistry of Liquids, ABSTRACTThe electrical resistivity of Sn-3.8Ag-0.7Cu-xCe (x takes 0, 0.2, 0.5 and 1.0 weight per cent) alloy as a function of temperature was measured by DC four-probe technique. Abnormal changes occurred on the resistivity-temperature (ρ-T) curves above the liquidus, which suggested that the temperature-induced liquid-liquid structure transition probably occurred in Sn-3.8Ag-0.7Cu-xCe melt, with some reversible characters. With the increasing of Ce, the melting range was expanded from 13.0°C to 24.2°C, and the resistivity increased sharply when the Ce composition increased to 0.2%, and then declined slightly. In addition, the temperature and behaviour of abnormal zone were affected by the different additions of Ce. ARTICLE HISTORY
