Abstract: This article studied A356/316L composites which were fabricated by infiltrating additively manufactured 316L lattices with molten A356. Various tests were conducted on the properties of the composites to determine if the two-step processing used to manufacture them avoided the issues that current fusion-based additive manufacturing techniques have. The thermal conductivity of the composites was determined with the transient plane source (TPS) technique. The results showed that the thermal conductivity of the composites had an inverse rule-of-mixture dependence on the volume fraction of the 316L cylinders.
