Abstract Scope |
AlSi10Mg alloy is commonly used in selective laser melting (SLM) due to its printability, relatively high thermal conductivity, low density and good mechanical properties. Thermal properties of AlSi10Mg are important to heat transfer applications including additively manufactured heatsinks, cold plates, vapor chambers and heat pipes. The thermal conductivity of samples fabricated in different orientations and energy densities will be discussed. The bulk thermal conductivity measurements were made via flash diffusivity, and local measurements were made with frequency domain thermoreflectance (FDTR). The properties are linked to the microstructural changes that occur in selective laser melted AlSi10Mg versus processing conditions. |
