Production techniques required for the severe forming of commercially available cross-rolled beryllium sheet are described. Configurations prepared with these techniques include straight bends, curved channels, hemispherical segments, and semicylinders with spherical ends. A minimum acceptable bend radius of 5 t, an optimum forming temperature of 1350 F, and shrink and stretch values of 9.0 and 13.0%, respectively, are established by statistical, metallographic, and dimensional analysis. The feasibility of the extreme forming of cross-rolled sheet material, as required for many aerospace applications, is clearly demonstrated.

The new and extended challenges presented by the NASA Space Station Program require different approaches from the current Shuttle Program. The twenty plus year life span of the space station itself will necessitate that maintenance and repair of critical items occur on-orbit. In order to conserve crew time there should be a central location for maintenance and repair activities which contains the needed tools, equipment, and support functions. This centralized location would be a Maintenance Work Station (MWS) applicable to maintenance and repair activities which would take place onboard Space Station. Maintenance tasks could range from card replacement to a complete disassembly of a unit in order to locate the problem. This MWS must be integrated into an overall space station data management subsystem. In particular, direct communication with the inventory control management subsystem is important.
