This article explored the relationship between structure and thermal conductivity in additively manufactured interpenetrating A356/316L stainless steel composites. The thermal conductivities were determined using the transient plane source (TPS) method. The thermal conductivity of a 43 vol% 316L composite was found to be 53 W/mK. This was a much lower value than what was predicted by the rule of mixtures approximation. This was believed to happen because residual porosity degrades ...
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 ...
Fiberglass is used inside car mufflers as a noise reducer and insulator. The insulating properties of the fiberglass eliminates the need for muffler heat shields, however to properly design vehicles without heat shields, it is important to know the thermal conductivity of fiberglass at high temperatures. A TPS Thermal Constants Analyzer was used to measure the thermal conductivity of glass fibers with diameters of 17 µm and 24 µm. Each sample was ...
