Summary

This metal sample, which is approximately 1 cm in diameter, is typical of the metals that were studied using the German designed electromagnetic containerless processing facility. The series of experiments that use this device is known as TEMPUS which is the acronym that stands for the German Tiegelfreies Elektromanetisches Prozessieren Unter Schwerelosigkeit. Most of the TEMPUS experiments focused on various aspects of undercooling liquid metal and alloys. Undercooling is the process of melting a material and then cooling it to a temperature that is below its normal freezing or solidification point. The TEMPUS experiments that used the metal cages as shown in the photograph, often studied bulk metallic glass, a solid material with no crystalline structures. We study metals and alloys not only to build things in space, but to improve things that are made on Earth. Metals and alloys are everywhere around us; in our automobiles, in the engines of aircraft, in our power-plants, and elsewhere. Despite their presence in everyday life, there are many scientific aspects of metals that we do not understand.
