As part of a wider program to develop solid-state ionically conducting materials for potential application in energy storage and conversion systems, the thermal diffusivity of a series of K-ion conducting electrolytes having the composition K x Mg x / 2 Ti 8-x / 2 O 16, where 1.6 ⩽ x ⩽ 1.8, was determined between room temperature and 700°C using a transitory heat-pulse technique. The alloys AZ31 and AZ61 are composed of magnesium, aluminum, and zinc. Phy. A.K. Chang and T.M. Scientific.Net is a registered brand of Trans Tech Publications Ltd COPYRIGHT ⓒ 2017 IVWorks Co., Ltd. ALL RIGHTS RESERVED. The thermal conductivity of all alloys increases with increasing temperature up to 300 °C. [5] SiC‐particle‐reinforced MgO composites have been fabricated by hot pressing, and the thermal diffusivities of the composites measured in the temperature range 200–1000°C using … Lee, M.D. [7] Heat transfer occurs through a combination of three methods; conduction, convection, and radiation.

Yang, L. Magne, G. Wang: J. of Cen. Vol. Vol. Abstract: In the present study, the thermal diffusivity of four sand casting magnesium alloys: Mg-9Al-1Zn, Mg-6Al-2Sr, Mg-9Al-1.5Ca-0.3Sr and Mg-9Al-2.2Ca-0.8Sr were studied. A.A. Luo: Mat. The p-type doping under the gate electrode was achieved by magnesium (Mg) thermal diffusion rather than the more usual inclusion as a precursor in the epitaxial material growth process. Hu: Mat. Liu, P. Peng, L. Chen, Y.J. Sand casting was performed at 730-780°C temperatures. The solubi1ity of Nd and Ce in Mg was studied by measuring their specific electric resistivity as functions of annealing and composition. The team comments: “The presented technique is commercially promising in the manufacturing of normally-off HEMTs with outstanding low gate leakage performance.” [9] Vol. Sand casting was performed at 730-780°C temperatures. The thermal diffusivity of the investigated alloys was chemical composition and temperature dependent … In this paper, the effects of magnesium alloys thermal conductivity and heat diffusivity … Schaffer, D. StJohn: J. of Light Met. Nave, P.L. [4] 473 (2008) p.16. Thermal diffusivity was measured by a LFA 427 Netzsch apparatus.

[8] Dahle, Y.C. Thermal diffusivity measurement techniques are easier carried out than the measurement of thermal conductivity and as such, thermal diffusivity measurements are often a means to the end of measuring thermal conductivity according to the equation k=\alpha \rho c with density and specific heat capacity known values. 43 (2002), p.127. L. Han, H. Hu, D. O. Northwood, N. Li: Mat. Thermal diffusion can theoretically fractionate Mg and Fe isotopes in the same direction, yielding a positive correlation between 26 Mg/ 24 Mg and 56 Fe/ 54 Fe (e.g., Richter et al., 2008, Richter et al., 2009, Huang et al., 2010).
