Finding thermodynamic properties for a Zn-Mg Alloy

[TimoD]

Hi!

I am using a Zn-Mg alloy (52% and 48% respectively) as a phase change material in a thermal energy storage system, but I have been unable to track down important properties, such as specific heats and thermal conductivity.

Is there any way to approximate these relatively accurately given the composition and temperature? Better yet, are there any sources out there with measured properties that I haven't seen?

Thanks in advance!
