“…The higher the thermal conductivity, the more effective the cooling is [11]. Some researchers have studied the thermal conductivity of as-cast and as-extruded Mg-based alloys [11][12][13][14][15][16][17][18]. A.…”

“…M.Y. Zheng et al recently have studied the thermal conductivity of as-cast and as-extruded Mg-Al/Zn alloys [15,16] and found that the anisotropy of thermal conductivity resulted from microstructure anisotropy because of the texture formed during extrusion [17]. The phase transformation and the different effects of Zn and Al on the thermal/ electrical conductivity have also been studied by F.S.…”

“…15) Recently, despite the increase in use of Mg alloys as heat sinks for LED lighting systems and as brackets for smartphones with large LCD screens, little is known about its thermal properties, especially its thermal conductivity. 6,7) With the increasing use of Mg alloys as lightweight components in mobile and LED heat sinks, its thermophysical properties, especially its thermal conductivity, plays an essential role in determining the performance of these Mg components. The thermal conductivity has an important function in the performance of Mg alloys and is essential for the selection of Mg alloys for specific applications.…”

The thermal conductivities of quaternary Mg-Zn-Ca-Y alloys have been investigated by evaluating the effect of adding Y on the Mg-4Zn-0.5Ca alloys, with an emphasis on developing new Mg alloys without compromising their thermal conductivities, processabilities, and mechanical properties.In this study, to improve the mechanical properties of the Mg-4Zn-0.5Ca alloy, Y was chosen as a strengthening element, and the effect of adding Y on the thermal and mechanical properties of the alloy was investigated. The thermal conductivities slightly decreased as the Y-content increased. However, the tensile yield strength and ultimate tensile strength improved as the Y-content increased. In addition, the average spiral flow lengths of the Mg-Zn-Ca-xY alloys were almost the same as that of the Mg-Zn-Ca alloy. The results of this study indicate that Mg-Zn-Ca alloys with more than 1 mass% Y exhibit better mechanical properties and thermal conductivities than gravity-cast AZ91 alloys.
