Equation of state measurements of additively manufactured Tantalum up to 450 GPa.

Additive manufacturing methods are promising for the at-scale production of components necessary to meet the challenge of high-repetition rate inertial fusion experiments. It is therefore necessary to verify if the behavior of additively manufactured materials such as Tantalum can be modelled using existing EOS tables, or if their unique microstructure changes the material response to shock compression. Here, we describe equation of state measurements taken on a two-stage light-gas gun which measured the absolute EOS of additively manufactured tantalum up to 450 GPa.
