Abstract

Certification and product qualification of an engineering component generally involves meeting engineering and physics requirements tied to its functional requirements.. In this paper, the results of a study quantifying the microstructure and the dynamic damage evolution of Tantalum (Ta) fabricated using an EOS laser-powder-bed machine are presented. The microstructure of the AM-Ta is detailed and compared / contrast to wrought Ta. The dynamic damage evolution and failure response of the AM-Ta material, as well as wrought Ta, was probed using flyer-plate impact driven spallation experiments. The differences in the spallation response between the AM and wrought Ta were measured using in-situ velocimetry as well as post-mortem quantification of damage in "soft-recovered" samples. The damage evolution of the AM and wrought Ta were characterized using optical metallography.
