Form No. 836 R5 ST 2629 10/91 OI_TRtBUTION _,_ "rFl_.,q r"tc'l_l I_u=l",l'r l=: U,N_ _..,-,-=_ ,¥ ¢ Ni-based HAYNES® 230 rM ALLOY has been studied to determine the effect of shock loading on the postshock quasista)!c, and dynamic mechanical response, and microstructural evolution. The compression properties of this material was studied in both the as-received and shock-loaded conditions at strain rates from 10-/s to 3000/s, and 77 and 293K. Damage evolution was documented via TEM, and correlated with the observed mechanical response. Changes in the deformation mechanisms and second phase distributions resulting from the shock pre-straining and subsequent testing are correlated with changes in the strain hardening behavior of the materials. Comparison of these results with shock loading results on pure Ni revealed distinct differences in strengthening and defect storage mechanisms.
