High thermal conductivity, high strength, and non-flammability have been achieved concurrently for the first time in Mg-4.5Al-2.5Ca, Mg-5Al-3Ca, Mg-6Al-4Ca, and Mg-4Al-2Ca-0.03Be (at%) alloys, produced by hot extrusion of heat-treated cast alloys.
High thermal conductivity, high strength and non-flammability have successfully been achieved concurrently for the first time in Mg-4.5Al-2.5Ca, Mg-5Al-3Ca, Mg-6Al-4Ca, and Mg-4Al-2Ca-0.03Be (at%) alloys, which are produced by hot extrusion of the heat-treated cast alloys. These alloys consist of alpha-Mg, and C36, C14 and C15 compounds, and exhibit a high thermal conductivity of 111-119 Wm(-1)K(-1), a high ignition temperature of 1343-1408 K and a high tensile yield strength of 318-363 MPa.
