Tiegelfreies Elektromagnetisches Prozessieren Unter Schwerelosigkeit; Electromagnetic Processing

The TEMPUS (Tiegelfreies ElektroMagnetisches Prozessieren Unter Schwerelosgkeit) facility is a research instrument designed to perform electromagnetic levitation studies in reduced gravity. TEMPUS was a joint undertaking between DARA, the German space agency, and the Microgravity Science and Applications Division of NASA. Specific objectives for the different investigations carried out by US Principal Investigators using this facility is categorized by different classes:
Class A: Studies of undercooling phenomena and the kinetics of nucleation (Prof. M. Flemings, MIT, Prof. R. Bayuzick, Vanderbilt Univ), Class B: Measurement of specific heat in liquid metals using an AC calorimetry technique (Prof W. Johnson, CALTECH), Class C: Measurement of viscosity and surface tension of undercooled metals (Prof. J. Szkeley, Prof. M. Flemings, MIT), Class D: Measurement of thermal expansion in undercooled materials (Prof W. Johnson, CALTECH).
In addition to the US Principal Investigators, available data from European investigations performed on TEMPUS and captured here include Viscosity and Surface Tension of Undercooled Metallic Melts (Dr. Egry, DLR, Germany), Thermophysical Properties of Undercooled Metallic Melts (Dr. Egry, DLR, Germany), Thermal Expansion of Glass forming Metallic Alloys in the Undercooled State (Dr. Samwer, Georg-August-Universitat Gottingen, Germany), and Thermodynamics and Glass Formation Undercooled Liquid Alloys (Dr. Wunderlich and Dr. Fecht, University of Ulm, Germany).

TEMPUS（德语全称：Tiegelfreies ElektroMagnetisches Prozessieren Unter Schwerelosgkeit）装置是一种用于在微重力环境下开展电磁悬浮研究的科研仪器。该装置由德国航天局（DARA）与美国国家航空航天局（NASA）微重力科学与应用部联合研发。美国首席研究员利用该装置开展的各项研究，其具体目标按不同类别划分：
Class A：过冷现象与形核动力学研究（麻省理工学院M. Flemings教授、范德堡大学R. Bayuzick教授）；Class B：采用交流量热法测量液态金属的比热（加州理工学院W. Johnson教授）；Class C：过冷金属的粘度与表面张力测量（麻省理工学院J. Szkeley教授、M. Flemings教授）；Class D：过冷材料的热膨胀测量（加州理工学院W. Johnson教授）。

除美国首席研究员的研究外，本数据集还收录了欧洲团队利用TEMPUS开展的相关研究数据，包括：过冷金属熔体的粘度与表面张力（德国航空航天中心Dr. Egry）、过冷金属熔体的热物理性质（德国航空航天中心Dr. Egry）、过冷状态下玻璃形成金属合金的热膨胀（德国哥廷根大学Dr. Samwer）以及过冷液态合金的热力学与玻璃形成（德国乌尔姆大学Dr. Wunderlich与Dr. Fecht）。
