Skylab Experiments, Volume 3, Materials Science.
National Aeronautics and Space Administration, Washington, DC.
Basic knowledge about Skylab experiments is presented in this book, one of a series, for the purpose of informing high school teachers about scientific research performed in orbit and enabling the teachers to broaden their basis for material selection. This third volume is concerned with the effect of a weightless environment on melting and resolidification of metals and semiconductor crystals and on combustion of solid flammable materials. The first section provides an introduction to crystal growth and a unifying background to the experiments. The second section is related to experiments on gallium arsenide crystal growth, vapor growth of IV-VI compounds, immiscible alloy compositions, radioactive tracer diffusion, microsegregation in germanium, growth of spherical crystal, whisker and reinforced composites, indirum antimonide crystals, mixed III-V crystal growth, halide eutectecs, silver grids melted in space, aluminum-copper eutectic, and classrooom demonstrations. The third section discusses zero gravity flammability, metals melting experiment, and exothermic brazing experiments. A description of the Materials Processing Facility is given in the fourth section. Materials are suggested to serve as an aid in developing future curriculum supplement materials. Included are a glossary and a bibliography. (CC)
