摘要：

The aim of this study is to investigate high thermal conductive materials such as metallic alloys for latent heat energy storage in CSP applications. For this purposes, two ternary eutectic alloys, Mg70Zn24.9Al5.1 and Zn85.8Al8.2Mg6, have been investigated. The structural and thermophysical characterizations have permitted to obtain their relevant properties needed for the design of thermal energy storage systems such as latent heat, melting/solidification temperatures, thermal conductivity and specific heat. Also, the thermal stability study has been accomplished in order to analyze the thermal performance of these materials after 700 cycles. Finally, the chemical compatibility tests between the Mg70Zn24.9Al5.1 alloy and the 304, 304L, 316 and 316L stainless steels have been performed. The results have confirmed the high potential of the investigated alloys for thermal energy storage application. (C) 2015 The Authors. Published by Elsevier Ltd.
