Abstract
Abstract The electrical conductivity, thermal conductivity and its relationship with the microstructure in Mg–5Sn alloy aged at 513 K for different aging times were investigated systematically in this paper. The results show that the electrical conductivity and thermal conductivity obviously increase with the increasing aging time, and its values increase from 10.25 × 10 6 S·m − 1 to 13.7 × 10 6 S·m − 1 , 87.5 W·m − 1 ·K − 1 to 122 W·m − 1 ·K − 1 after aging treatment for 120 h, respectively. Meanwhile, it is found that there exist quite different relationships between unit cell volume and thermal conductivity in early and later aging stages.
