Several molten alloys were investigsted, including systems exhibiting considerable mutual solubility of the components in the solid state, such as Al-- Cu, Pb--Sn, Al--Ge, Al--Si, Pd--Zn, Al--Ag and Bi--Sn and one consisting of mutunally insoluble components, Al-- Sn. A definite correlation has been established between the electrical resistance and the phase diagram of the alloys. In the Al--Cu and the Pb--Sn systems the maximum of the resistance curve corresponds to the saturation limit of the solid solution. A sudden change is noted in the resistance of alloys whish crystallize in.a. wide temperature range, at temperatures at which there is at least 50% of the liquid phase present in the solid-liquid mixture. Such a resistance change is completely absent in the case of eutectic mixtures, such as Bi--Sn and Bi--Pb, the components of which exhibit an opposite behavior with respect to conductivity when they undergo melting. This behavior which is noted at 55 at.% Bi, corresponding to the eutectic, may be due to the collection of dissimilar atoms in the liquid eutectic. (TTT)
