This article aimed to compare the effects of casting processes and heat treatments on the thermal conductivities of the Al-10 wt% Si-0.6 wt% Cu-0.9 wt% Fe-0.7 wt% Zn aluminum alloy by using the gravity-casting and die-casting processes. The thermal conductivities were measured using an thermal analyzer which operates using the transient plane source (TPS) technique. From the TPS technique, it was observed that that the gravity-cast materials achieved a higher ...
This study investigated new sol-gel methods in the fabrication of Al₂O₃ - SiO₂ composite aerogels. Compared to conventional methods, the Al₂O₃ - SiO₂ composite aerogels were prepared and mixed together. Thermal conductivity of the composite aerogels was measured by an instrument, using a transient plane heat source method....
