Determining the Thermal Conductivity of Additively Manufactured Metal Specimens

This paper presents a method for experimentally determining the thermal conductivity of additively manufactured specimens. Selective laser melting was used to fabricate two metal rods - one from an aluminum alloy (AlSi10Mg) and the other from silicon steel (Fe-3.7%w.t.Si) powder. For measuring the t...

Description
Summary:This paper presents a method for experimentally determining the thermal conductivity of additively manufactured specimens. Selective laser melting was used to fabricate two metal rods - one from an aluminum alloy (AlSi10Mg) and the other from silicon steel (Fe-3.7%w.t.Si) powder. For measuring the thermal conductivity, an experimental setup is designed and the measurements are carried out. According to the experimental results, the thermal conductivities of the aluminum and steel rods are 107.8 \pm 3.95 and 25.97 ± 0.86W /m/K respectively.
