Bubbles and semiconductors evaluated on space station. (Materials Science/R&D).
Advanced Materials & Processes, August, 2002
Defects in metal alloys and semiconductor crystals caused by bubbles that solidify from the melt are subjects of the materials science experiments that are to be carried out on the International Space Station, reports NASA Marshall Space Flight Center, Huntsville, Ala.. The Space Shuttle Endeavour is to deliver two novel furnaces and more than 20 ampoules filled with material samples for materials science experiments.
The furnace will melt samples of a transparent modeling material called succinonitrile in an experiment to view the behavior of bubbles in a microgravity environment. That should provide useful information on how bubbles that form in molten metal will behave in a similar environment. Another experiment will study solidification of semiconductor...
