Microstructure and Thermal Conductivity of As-Cast and As-Solutionized Mg-Rare Earth Binary Alloys

- The influence on thermal conductivity (TC) was drawn as: Ce < Nd < Y < Gd.
- TC of both as-cast and as-solutionized Mg-RE alloys decreased with concentration.
- Solutionizing treatments decreased TC of Mg-Nd, Mg-Y and Mg-Gd alloys, except for Mg-Ce alloys.
- The maximum solid solubility of elements in the α-Mg matrix cannot be neglected.
