Combined ab initio, experimental, and CALPHAD approach for an improved thermodynamic evaluation of the Mg-Si system

► Thermodynamic modeling of the Mg-Si system. ► Finite temperature DFT + quasiharmonic approximation for Gibbs energy of Mg2Si. ► DSC measurement of heat capacity and enthalpy of melting of Mg2Si. ► The Gibbs energy of Mg2Si reliably described.
