摘要

The electrical resistivity of liquid In-Sn alloy was measured by a dc four-probe method. In a relatively low-temperature zone above liquidus, resistivity changes discontinuously; only the changing trend is altered, whereas resistivity changes sharply in the high-temperature zone and the changing pattern is completely different from the ones at low temperature. The unusual change of resistivity reflects the alteration of the mean free path L-0 of conduction electrons and also the electron transport properties. Consequently, we assume that structural changes might occur in the continuous heating process. Transition temperatures are different for In-Sn melts with various compositions. The resistivity behaviour of eutectic composition is distinguished from others and its transition temperature is the lowest.
