Shock Hugoniot and a broad-range multiphase EOS of Ti-6Al-4V to more than 1 TPa.

POSTER

Abstract

Titanium and its alloys are a fascinating family of metals with excellent mechanical and biocompatibility properties with applications in aerospace, defense, biomedical and more. In this work we focus our attention on Ti-6Al-4V, commonly referred to at Ti64. We use ab initio molecular dynamics (AIMD) simulations, which we validate with experimental shock data to over 1 TPa on Sandia's Z machine, in order to develop a high-fidelity, multiphase Equation of State for (EOS) Ti64, spanning a broad range of temperature and pressures. The resulting EOS is suitable for use in hydrodynamic simulations involving shock compressions of solid materials.
