Electrical resistivity of Ni - In liquid alloys

Abstract

The electrical resistivity of liquid alloys has been measured as a function of temperature (between the melting point and ) and of concentration in 10 at.% steps over the whole phase diagram. The concentration dependence of the resistivity shows a maximum at about 60 at.% nickel. In the neighbourhood of this concentration, the temperature dependence changes sign. We have interpreted semi-quantitatively our experimental results using the extended Faber - Ziman theory within the t matrix formalism.

Are there phase transitions in liquid metallic alloys?

“…A second observation is that Xi et al [1] and Yu et al [2] are far from our measurements (nearly 10% below our curves). Thus we have also reported on figures 9, 10 and 11 experimental results of other authors [11,12,13,14,15,16,17,18] which are near our values. Such a systematic difference is generally due to the calibration of the constant of the cell.…”

Electrical resistivity and absolute thermoelectric power of liquid indium-nickel-manganese ternary alloys

“…For the binary In-Mn alloy, the resistivity increase with manganese concentration is important, as has been observed by Gasser [1]. The resistivity of In-Ni [3] increases also with the transition metal concentration, but at a lower rate than for In-Mn. The resistivity of the In 46 Ni 54 alloy at 1000 • C is 99 µ cm while the interpolated resistivity of In 46 Mn 54 obtained from the measurements made by Gasser [1,7] is of about 124 µ cm.…”

“…Until now the absolute thermoelectric power (ATP) of manganese had not been measured due to its reactivity with the container and the electrodes (liquid manganese at 1250 • C dissolves all metals apart from tungsten) and to the high melting point of the transition metal. However, from the extrapolations of the thermopowers of the binary systems In-Mn [2] and In-Ni [3,4] it can be expected to be positive.…”
