This article studied the microstructural features of thorium-52 wt.% uranium alloy (Th-52U). Several thermal properties were also evaluated to assess the use of this alloy as a prospective fuel. The transient plane source (TPS) technique was used for evaluating the thermal conductivity of Th-52U alloy using slab specimen geometry. The experimentally determined thermal conductivity value of Th-52U alloy was found to be 25.6 W/m°C, which is ...
Thermophysical properties of a uranium-6 wt. % zirconium alloy were investigated at high temperatures to evaluate the performance of the alloy as a driver fuel for a liquid-metal cooled fast reactor. Of particular interest to the authors were the coefficient of thermal expansion, the specific heat, and the thermal conductivity of the alloy....
Using the transient plane source (TPS) technique, the authors investigated the thermal properties of a series of yttria-stabilized zirconia (YSZ) thermal barrier coatings (TBCs). The YSZ coatings had varying amounts of impurities (Zr, Y, Si, Al oxides) and the amount of impurity affected the post-spray properties of the coating. TBCs are exposed to high temperatures during their regular operation, which can lead to the degeneration of the coating if the ...
In order to prepare more thermally resistant materials for use as thermal barrier coatings, the authors performed experiments on yttrium stabilized-zirconia (7YSZ) in order to investigate sintering resistance and phase stability at high temperatures. It was theorized that the main factor that affected the sintering resistance and phase stability at high temperatures was the concentration of impurities (Al2O3 and Si2O) present in the 7YSZ. Therefore in this report ...
