| Abstract Scope |
In order to attain high undercoolings in reactive molten metal alloy systems, containerless processing is used in conjunction with high-speed digital videography and radiation pyrometry. On ground, electrostatic levitation provides access to a quiescent melt while electromagnetic levitation provides access to turbulent stirring. To investigate conditions between these extremes, electromagnetic levitation is conducted in Low Earth Orbit. This presentation highlights the evaluation of rapid solidification of undercooled ferrous alloy investigations which have flown on the Space Shuttle Columbia and in the Columbus module of the International Space Station. In particular, emphasis will be placed on new solidification theories developed to explain how phase transformation kinetics are influenced by melt convection. |
