| 内容記述 | tThe thermophysical properties of lead lithium alloy (Pb–Li) are essential for the design of liquidPb–Li blanket system. The purpose of the present study is to make clear the density, the thermaldiffusivity and the heat conductivity of the alloys as functions of temperature and Li concentration.The densities of the solid alloys were measured by means of the Archimedean method. The densitiesof the alloys at 300 K as a function of Li concentration (0 at% < Li< 28 at%) were obtained in theequation as (300 K)[g/cm3] = −6.02 × 10−2× Li+ 11.3. The density of the liquid alloys was formulatedas functions of temperature and Li concentration (0 at% < Li< 30 at%), and expressed in the equationas [g/cm3] = (9.00 × 10−6× T − 7.01 × 10−2) × Li+ 11.4 − 1.19 × 10−3T. The thermal diffusivity of Pb,Pb–5Li, Pb–11Li and Pb–17Li were measured by means of laser flash method. The thermal diffusivity ofPb–17Li was obtained in the equation as ˛Pb–17Li[cm2/s] = 3.46 × 10−4T + 1.05 × 10−1for the temperaturerange between 573 K and 773 K. The thermal conductivity of the Pb–17Li at the temperature of 773 Kwas newly obtained and expressed in the equation as [W/mK] = 4.47 × 10−2 Li2− 0.08 Li+ 14.9.The dependence of Li concentration on the thermal diffusivities of the alloys was larger at highertemperature. The temperature dependence of the thermal conductivities of the alloys was larger whenthe Li concentration in the alloys was higher. | |||||
