Abstract

The thermal conductivity of the Mg-1Mn-2Zn-1Nd alloy aged at 200C for 12, 24 and 48 h was investigated for the applications of heat dissipation. The microstructures were examined by X-ray diffraction analysis, optical light and scanning electron microscopy. The thermal conductivity of the Mg alloy was measured at room temperature by laser flash method. The hardness was measured by with a load force of 29.4 N and dwell time of 30 s.The experimental results indicate that the hardness of Mg-1Mn-2Zn-1Nd alloy first increases and then decreases with the aging time. The thermal conductivity of the Mg alloy slowly increases with aging time and its maximum value exceeds the critical value (120 W/(m•k)) of wrought Mg alloys for the applicationsof heat dissipation.The aged Mg-1Mn-2Zn-1Nd alloy is expected to be a good candidate of heat dissipating alloys.
