Influence of peak pressure on the substructure evolution and shock wave profiles of Ti-6Al-4V
The object of the present study was to investigate the infleunce of peak pressure on the residual structureproperty relationships and the wave profile behavior of shock-loaded Ti-6-4. A further aim of the present work was to determine if the alpha to omega phase transformation occurred in Ti-6-4 using /open quotes/real time/close quotes/ VISAR and post-mortem shock recovery techniques. The following conclusions can be drawn: over the velocity range investigated no evidence of an alpha to omega phase transition was observed in Ti-6-4 with either VISAR wave profiles or shock recovery experiments; increasing peak pressure results in an increased dislocation density and yield strength in shock-loaded Ti-6-4; deformation of the (1121) type, are observed in the 10 and 13 GPa; the low pressure Hugoniot for Ti-6-4 is given by U/sub s/ = 5.123 kms + 1.083 U/sub p/ for U/sub p/ < 1.4 kms; the high pressure relation is given by U/sub s/ = 5.030 + 1.056 U/sub p/. 9 refs., 5 figs.
