ML00144 — Impact of a .380 Winchester on Ti64 PlateM - Ti6Al4VP - Rolled PlateAp - StructureCd - Non-Pierced
Micrographic detail by SEM, showing the beta phase EDS analysis was conducted in this microstructure and the results indicated 90.8%Ti + 6.8%Al + 2.4%V for the alpha phase (the dark grains as a matrix); and 84.7%Ti + 5.2%Al + 8.8%V + 1.2%Fe for the beta phase (light with aicular morphology inside the phase).
