Abstract
The crystallization properties of electrodeposited amorphous alloys Co1-xPx (enthalpy of crystallization, shape of the DSC thermopower signal. X-ray diffraction, resistivity) show that a local chemical order exists in these phases. This local chemical order at the eutectic composition implies the existence of a double miscibility gap in the metastable liquid equilibrium diagram. This work shows the relaxation effect in the amorphous state for all concentrations other than the eutectic composition. This relaxation effect should be interpreted as the recovery of the system, which tends to return to the demixed metastable liquid phase.
