摘要

利用两台静电悬浮(ESL)设备测量了ni基CMSX-4 - Plus在一定温度范围内的密度、热膨胀系数、表面张力和粘度。地面试验是在超高真空条件下使用NASA MSFC ESL设备进行的，天基试验是在172千帕氩气气氛下使用JAXA ELF进行的。测量值与其他各种设施的现有文献数据进行了比较。本研究的重点是利用不确定度测量表达指南(GUM)原理对实验数据进行详细的不确定度分析，以测量被测特性的准确性和精密度。本研究的结果已被用于量化两个ESL设施的表现。

A quantitative comparison of thermophysical property measurement of CMSX-4� Plus (SLS) in microgravity and terrestrial environments

Density, thermal expansion coefficient, surface tension and viscosity of Ni-based CMSX-4� Plus have been measured for a range of liquid temperature by utilizing two Electrostatic levitation (ESL) facilities. Ground-based tests were conducted using the NASA MSFC ESL facility in Ultra High Vacuum and space-based tests were conducted using JAXA ELF in a 172 kPa Argon gas atmosphere. The measured values were compared to the available literature data from various other facilities. This study focuses on a detailed uncertainty analysis of the experimental data to measure the accuracy and precision of the measured properties using Guide to the expression of Uncertainty Measurement (GUM) principles. The findings from this study have been used to quantify the performance of the two ESL facilities.

期刊介绍： High Temperatures – High Pressures (HTHP) is an international journal publishing original peer-reviewed papers devoted to experimental and theoretical studies on thermophysical properties of matter, as well as experimental and modelling solutions for applications where control of thermophysical properties is critical, e.g. additive manufacturing. These studies deal with thermodynamic, thermal, and mechanical behaviour of materials, including transport and radiative properties. The journal provides a platform for disseminating knowledge of thermophysical properties, their measurement, their applications, equipment and techniques. HTHP covers the thermophysical properties of gases, liquids, and solids at all temperatures and under all physical conditions, with special emphasis on matter and applications under extreme conditions, e.g. high temperatures and high pressures. Additionally, HTHP publishes authoritative reviews of advances in thermophysics research, critical compilations of existing data, new technology, and industrial applications, plus book reviews.
