“…It is worth mentioning that other non-conventional processes have been applied to tungsten aside EDM and ECM. These processes include water jet cutting [99], laser cutting [100][101][102], and laser drilling [103,104]. A discussion of studies and findings from these non-conventional machining techniques is provided next.…”

Tungsten is a refractory metal with the highest melting temperature and density of all metals in this group. These properties, together with the high thermal conductivity and strength, make tungsten the ideal material for high-temperature structural use in fusion energy and other applications. It is widely agreed that the manufacture of components with complex geometries is crucial for scaling and optimizing power plant designs. However, there are challenges associated with the large-scale processing and manufacturing of parts made from tungsten and its alloys which limit the production of these complex geometries. These challenges stem from the high ductile-to-brittle transition temperature (DBTT), as well as the strength and hardness of these parts. Processing methods, such as powder metallurgy and additive manufacturing, can generate near-net-shaped components. However, subtractive post-processing techniques are required to complement these methods. This paper provides an in-depth exploration and discussion of different processing and manufacturing methods for tungsten and identifies the challenges and gaps associated with each approach. It includes conventional and unconventional machining processes, as well as research on improving the ductility of tungsten using various methods, such as alloying, thermomechanical treatment, and grain structure refinement.

“…Using a CO 2 laser with nitrogen as an assist gas, Begic-Hajdarevic et al [101] observed the influence of the laser power and cutting speed on surface roughness. Cutting speeds of 1000, 1500, and 2000 mm/min and powers of 1500, 1750, and 2000 W were considered.…”
