| Abstract Scope |
Additive manufacturing (AM) of metals presents potential niche advantages over traditional manufacturing, with the potential for revolutionary design and production for various applications. For additive manufacturing of metallic materials, the certification and qualification paradigms continue to evolve. Accordingly, design, manufacture, and thereafter implementation and insertion of AM materials to meet dynamic loading engineering applications requires detailed quantification of the constitutive (strength and damage) properties of these evolving materials, across the spectrum of metallic AM methods, in comparison/contrast to conventionally- manufactured metals and alloys. In this talk, an overview of the structure/property behavior of dynamically / shock-loaded AM materials including 304 and 316 SS, Ti-6Al-4V, and Tantalum will be overviewed. Finally, an on-going systematic study linking the effects of AM processing parameters, including varying laser power, laser speed, hatch spacing and layer thickness on the spallation behavior of 316L SS will be discussed. |
