| Abstract Scope |
Several studies has been done on the shock-induced mechanical response of the commercial Ti6Al4V sample but studies on its counterpart Ti6Al4V sample produced using Additive Manufacturing (AM) is quite limited. In this study, a high energy pulsed laser (1064 nm, 10 Hz and 8-10 ns) was used to induce a shock wave on a Ti6Al4V sample while varying the sample thickness from 0.5 to 1.5 mm, respectively. These Ti6Al4V samples were produced using an AM process called selective laser melting (SLM). A velocity interferometer system for any reflector (VISAR) system was employed to study the mechanical response of the Ti6Al4V samples. The mechanical properties and Hugoniot elastic limit (HEL) of the AM Ti6Al4V were determined using the VISAR back free surface velocity profile. Furthermore, the shock wave parameters were determined as well. Comparison study of the mechanical response and measured HEL for the commercial and AM Ti6Al4V will be discussed. |
