摘要
The thermodynamic description of Mg-Al-Ca-Sn quaternary system in the Mg-rich region was developed on the basis of both our previous work and literature data on the key constituent ternaries, including Mg-Al-Ca, Mg-Al-Sn and Mg-Ca-Sn systems. Using this description coupled with the Scheil model, the solidification paths of Mg-Ca-Sn ternary alloys and Mg-Al-Ca-Sn quaternary alloys were calculated, which are in good accordance with the experimental results from directional solidification obtained by us.
