Concept development evaluation for John Deere/UA STS middeck experiment locationThe purpose of this effort was to consider and evaluate some specific concepts for performing a number of extremely low gravity (i.e., microgravity) experiments involving the directional solidification of samples of high carbon, cast iron alloys. The specific experiments considered herein were conceived to permit scientific investigation of the resultant microstructures and mechanical properties of the test samples after the microgravity environment processing. This study was limited to consideration of the NASA/MSFC furnace payloads, referred to herein as the Automated Directional Solidification Furnace (ADSF) systems. Three ADSF systems were reviewed and are as follows: (1) Low temperature ADSF (ADSF-1); (2) High temperature ADSF (ADSF-2); and (3) Advanced ADSF (AADSF).
