Short description

Simulation methodologies for the designing of novel metallic alloys to be used for different applications (as thermal energy storage media in this project). Small prototype and Semi-Industrial Scale metallic alloy synthesis processes. 

The design of the novel metallic alloys to be used as PCM for DSG applications was done using Thermo-Calc software package for the calculation of thermodynamic and phase equilibria using the SSOL4 thermodynamic database. This methodology has been applied by Tecnalia previously to the project fot the designing of novel alloys. 

The semi industrial scale metallic alloy synthesis has been done by using a Vacuum Induction Melting Furnace. Characterizations have been performed by: optical microscopy (OM), scanning electron microscopy(SEM) with energy dispersive spectroscopy (EDS) and X-ray diffractometry (XRD). Together with this a complete thermophysical characterization will be performed by Differential Scanning Calorimetry (DSC) Simultaneous Thermogravimetric (TG) and Differential Thermal Analysis (DTA) and thermal conductivity. These techniques have been applied by Tecnalia in many different projects previously to the project.
