The Influence Of additive Erbium on Thermodynamic Behaviors of Aluminum - Zinc Alloys

Thermal conductivity, specific heat capacity, enthalpy, entropy and free Gibbs energy of Zn55Al and Zn5Al alloys with additive erbium were studied using a new device according to cooling newton's law. It was observed that with increasing temperature, specific heat capacity, enthalpy and entropy of the alloys increase. A sharp reduction in thermal conductivity and specific heat capacity showed that in all the systems, there is the second order phase transformation about temperatures of 520 to 530 K. The thermodynamic factors are calculated.
