“…The d.c. electrical resistivities of liquid Ag-Cu alloys have been reported by Saadeddine and Gasser. [28] Assuming that liquid silver, copper, and Ag-Cu alloys each have one free electron per 2nk ϭ 2 p 2 ϩ 1 2 [4] atom, the effective electron density can be obtained using the atomic density of the metals and alloys. The atomic densities of the alloys were estimated from the linear interpowhere is the angular frequency of the light, p is the plasma lation between the atomic density of pure elements.…”

The wavelength and composition dependencies of normal spectral emissivities for liquid Ag-Cu alloys have been measured over a wavelength range between 450 and 1500 nm at temperatures from 1273 to 1423 K in a cold crucible furnace. The spectral emissivities abruptly increase in the visible region with decreasing wavelength. The wavelength at the abrupt increase in the emissivity shifts to a shorter wavelength as the concentration of silver in the alloy increases. This suggests that the abrupt increases are attributed to the direct interband transition, and the energy gap between the d band and the Fermi level increases with an increase in silver concentration in the alloy. To the contrary, the spectral emissivities in the infrared region were found to exhibit weak negative wavelength dependencies, which are attributed to the intraband transition. The composition dependencies of spectral emissivities observed in the infrared region have been explained by the Drude model.

With the help of non-contact measurement, electrical resistivity of Cu, Ni, Sb has been measured to study the influence of short range order on electrons scattering in the normal and undercooled liquid state. Till the maximum undercooling, linear resistivity-temperature dependence is obtained in Cu and Ni melts. Nonlinear resistivity behavior is obtained in undercooled liquid Sb till a maximum undercooling of about 60 degree. The increase in viscous flow activation energy reveals structure transition in Sb melts. A drop in resistivity of Cu melts is obtained accompanying the recalescence. The abrupt jump in resistivity of Sb reveals the rapid growth of Peierls distortion during rapid solidification process.
