Abstract
The electrical resistivity and thermal conductivity of as-cast pure Mg with different grain sizes prepared by ultrasonic treatment were measured in the temperature range of 2-320 K. The grain size has little effect on residual electrical resistivity, but the different samples exhibit different temperature coefficients of resistance. The maximum of thermal conductivity 665 W/(m·K) appears at ∼20 K where the different grain sizes shows the biggest difference. Less effect of grain size on the thermal conductivity can be observed at room temperature.
