The abnormal changes of electrical resistivity in liquid Pb–In alloys

Are there phase transitions in liquid metallic alloys?

“…To compare our results with Xi et al [1] and Yu et al [2], we try to reproduce their experiments by using the same experimental method and process. Our alloys were prepared at the expected composition from pure elements (purity: 99.999% for In, Bi and Pb), melted under vacuum in a quartz tube, heated, shacked, then cooled rapidly at room temperature under argon pressure in order to get an alloy "as concentration homogenous" as possible.…”

“…they (and we) did not consider as correct the first heating measurements. Having developed since many years an experimental design (cell(s) + measurement methods) able to make accurate resistivity measurements, we feel necessary to check if we observe the same behaviour as that reported by Xi et al [1] and Yu et al [2] and others [3 to 7] by using our experimental cell and the same experimental process than the Hefei's group.…”

“…They observed a drastic change of the temperature coefficient of the resistivity of four alloys, the most important was observed for Bi 52.73 In 47.27 at% 2 . The authors suggest a significative change of the short range order in different Bi-In melts.…”

“…The authors suggest a significative change of the short range order in different Bi-In melts. Yu et al [2] measured seven different compositions of liquid In-Pb between the melting point and 1200°C.…”

“…The resistivity varies in the range from about 100,000 µΩ.cm to 200 µΩ.cm and the breaking of the bonds 2 All concentrations are given in atomic %. The values in the literature given in mass% have been converted to atomic%.…”
