Quasicrystal Al63Cu25Fe12 Melting Nearby Resistivity and Viscosity Properties Research
A four-probe dc method for measuring the electrical resistivity of liquid quasicrystal Al63Cu25Fe12 was investigated in this article and found out that the resistivity of the melt temperature negative factors. Resistivity in alloy melting temperature near the lower interval occurred in phase I and λ, but is not happen to shift in β phase. That would not cause phase change of electronic transport, may be held without fracture, and held the bond length is changed. The viscosity of liquid quasicrystal Al63Cu25Fe12 was tested by using torsional oscillation viscosity measurement. Anomalous change at the temperature of (1401-1473)K occurred from the viscosity-temperature cures, some liquid-liquid change has taken place at this temperature.
