| Abstract Scope |
Additive manufacturing (AM) is particularly promising for manufacturing complex geometries from tungsten and other refractory metals, which are difficult to form using traditional processes. In this study, tungsten lattices were additively manufactured using various laser energy densities. These lattice structures have promising applications in both fission and fusion systems for heat transfer in applications which require radiation resistance at high temperatures. The goal of the work is to investigate the ability to adjust lattice type and printing parameters to vary the resulting fluid flow and mechanical properties of these lattices. To that end, lattice feature sizes were characterized using scanning electron microscopy and flow tests were performed with water and N2 to characterize the pressure drop across these samples. This work will help inform the development of tungsten lattices for nuclear systems, where tungsten is already of major interest for fusion systems for plasma facing and high thermal load structures. |
