Abstract

In the present work, the effects of Sn, Ca additions on thermal conductivity were investigated in as cast Mg–Sn–Ca alloys. The measured values of thermal conductivity of Mg–3Sn–xCa alloys obviously increased from 85.6 to 126.3 W m− 1 K− 1 with the increasing Ca from 0 to 1.5 wt-%, and then decreased to 98.3 W m− 1 K− 1 with the 2.5 wt-% Ca. In addition, the thermal conductivity of the Mg–Sn–Ca (Sn/Ca atomic ratio of 1) alloys decreased slightly from 154.2 to 132.1 W m− 1 K− 1 with the increasing Sn, Ca. Meanwhile, the microstructures of the selected alloys were discussed in detail, suggesting that the solute atoms that caused lattice distortion had greater effect on thermal conductivity compared with the second phases formed in as cast Mg–Sn–Ca alloys.
