thermal conductivityAluminium alloys are broadly used in the automotive industry, mainly in power train applications (cylinder head and cylinder blocks), where efficient heat extraction is critical for engine efficiency. This work presents the results of a series or trials carried out to improve the ...
The thermal diffusivity of the magnesium alloys, AZ31 and AZ61, was measured over the temperature range from -125 A degrees C to 400 A degrees C. The alloys AZ31 and AZ61 are composed of magnesium, aluminum, and zinc. The thermal conductivity gradually increased with temperature. The densities...
The thermal conductivity of aluminum alloys is mainly influenced by alloying elements, including their species, content, and existing state, but the influence level of each factor is not quantified. In this work, we propose a quantitative relationship between the thermal conductivity of aluminum alloys...
8.4.1.2Alloys Thermal conductivityof pure elements decreases strongly withT, whether metallic (Fig. 3.6B) or semiconducting (Fig. 8.1). In contrast, alloys have thermal conductivity that increases withT(Fig. 8.1) becauseDis flat or increases withT(Criss and Hofmeister, 2017), whereas heat capaci...
The results of heat conductivity measurements at liquid air and liquid hydrogen temperatures on alloys of silver with small amounts of manganese, indium and lead are discussed as a preliminary to further investigations at temperatures below 14°K. The thermal resistivity is not linear with the conce...
Thermal transport in bulk ternary III-V arsenide (III-As) semiconductor alloys was investigated using equilibrium molecular dynamics with optimized Albe-Tersoff empirical interatomic potentials. Existing potentials for binary AlAs, GaAs, and InAs were optimized to match experimentally obtained acoustic-phonon...
Validity of Wiedemann-Franz-Lorenz Law leads to the knowledge of thermal conductivity indirectly by the electrical conductivity measurements. Studies on copper-manganese alloy system carried out indicated the non-availability of Wiedemann-Franz-Lorenz Law. High specific resistance of these alloys coupled ...
Thermal conductivity and electrical resistivity of Nb Ti alloys at low temperatures 喜欢 0 阅读量: 55 作者:YF Bychkov,R Herzog,IS Khukhareva 摘要: Results are presented of an experimental study of the thermal conductivity, electrical resistivity, critical temperature and upper critical field of ...
Although Ag is known as a material that has one of the highest thermal conductivities, the thermal conductivity of liquid Ag–In alloys is much lower than that of pure liquid Ag (177 W/mK at 1273 K), but almost the same or less than that of liquid In (59.2 W/mK at 1273 K) in ...
Low-temperature thermal-conductivity results are presented on two Cu +9-at.%-Al polycrystals which show that fast-neutron irradiation has two effects on a coldworked sample of this alloy. In the well-annealed specimen, irradiation produced defects which scatter long-wavelength phonons, giving a we...
