Parallel shock recovery and wave profile experiments have been performed that exhibit a Bauschinger effect in Si-bronze shocked to 10 GPa. The unloading wave profile in Si-bronze exhibited a quasi- elastic release that had greater departure from the ideal elastic- plastic response than the pure copper samples. The reload mechanical response of Si-bronze that was preshocked to 10 GPa exhibited less hardening than the annealed material to an equivalent strain while the reverse hardening effect was true for copper. The importance of a microstructurally-controlled Bauschinger component to defect storage during the shock process is discussed in light of shock recovery, wave profile, and deformation substructure results. 8 refs., 3 figs.
