This article aimed to obtain more information on the microstructural, mechanical, thermo-physical, and ageing aspects of the Th-3 wt.% U alloy. The thermal conductivity of the Th-3U alloy was found at room temperature using the transient plane source (TPS) technique. It was found that the room temperature thermal conductivity of Th–3U alloy (35.6 W/m◦C) is superior to that of unalloyed uranium, existing oxide, and metallic fuel materials....
In this paper, polyamide (PA, composed of at least 60% renewable materials) was used as a polymer matrix to prepare PA-hexagonal boron nitride (hBN) polymer composites with varying hBN contents. Two different PA samples were used in this study: a low viscosity grade PA (PA-30), as well as a high viscosity grade PA (PA-90). The composite polymers were tested to evaluate their thermal, physical, and mechanical properties. It was concluded that ...
The high temperature fire resistance of vanadium is not well documented, so its properties are usually approximated to the same as conventional structural steels. The goal of this study is to determine the properties that influence the fire resistance of structural steel, thermal conductivity, specific heat and thermal elongation. Thermal conductivity and specific heat were both determined through a transient plane source (TPS) method. Vanadium and A36 steel were both ...
Phosphosilicate ceramics with varying compositions were synthesized through the sol-gel process and the thermal conductivity of the samples was measured using the transient plane source (TPS) method. Results showed that the thermal conductivity of phosphosilicate ceramic powder was low, but increased slightly with phosphorous concentration. The low thermal conductivity of the ceramics could be useful in thermal barrier applications....
The goal of this study was to obtain information on thermal properties of three types of concrete over a wide temperature range (20°C to 800°C). The three types of concrete are: high-strength concrete (HSC), self-consolidating concrete (SCC) and fly-ash concrete (FAC). The thermal data collected included thermal conductivity, specific heat and thermal expansion of the concrete samples using the TPS method. The effect of steel, propylene and other hybrid fibers ...
