The effects of shock wave compaction on the transition temperatures of A15 structure superconductors
A 1974 NASA technical report by G. H. Otto on shock wave compaction of A15-structure superconductors and its effect on transition temperatures, issued for researchers and engineers in materials and cryogenics. The illustrations pair line diagrams of test apparatus—a lettered, keyed schematic of a hatched sample rod with an explosive charge and centerline axis—with square halftone micrographs of fractured, granular metal surfaces, offering keyed technical callouts and coarse grey textures.
