Analysis of structural changes and high-heat-flux tests on pre-damaged tungsten from tokamak melt experiments
TL;DR: In this article, the characteristics of W plasma-facing components under high heat fluxes were investigated in view of the material choice for the divertor in future fusion devices, and the material structure after exposure and the cracking thresholds and patterns under repetitive transient thermal loads were investigated.

Additive manufacturing of high density pure tungsten by electron beam melting
TL;DR: In this paper, a selective electron beam melting and a base temperature of 1000°C of the powder was used to produce tungsten with a theoretical density of 99% without the need of any post-treatment like a second melting step or a redensification by e.g. hot isostatic pressing (HIP).
