Thermal conductivity, electrical resistivity, and thermopower have been measured for several aerospace alloys: titanium alloy A110-AT, aluminum alloy 7039, Inconel 718, and Hastelloy X. Tables and graphs of the measured properties and Lorenz ratio are presented over the range 4 to 300 K. Comparisons to other measurements and theoretical analysis of the data are included. The uncertainties of the property data are estimated as (1) 0.7 to 2.5 percent for thermal conductivity, (2) 0.25 percent in electrical resistivity, and (3) about 0.1/ V/K in thermopower.
已对几种航空航天合金测量了热导率、电阻率和热功率，这些合金包括：钛合金A110 - AT、铝合金7039、因科镍合金718和哈氏合金X。给出了在4至300 K范围内测量特性和洛伦兹比的表格及图表。还包括与其他测量结果的比较以及对数据的理论分析。特性数据的不确定度估计如下：(1)热导率为0.7%至2.5%，(2)电阻率为0.25%，(3)热功率约为0.1 / V/K。
