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 ...
Although much research had been conducted to improve the ability of engine cylinder heads to respond to thermal stresses, not much research had been conducted on reducing thermal stresses. The authors set out to determine the thermal conductivity of a commercial aluminum 319 type alloy cylinder head with the future goal of improving the thermal conductivity of cylinder heads to better reduce the stress induced by increasing temperature. The cylinders were ...
