Abstract Scope |
Tungsten has recently piqued interested as the potential precursor for L-PBF techniques. However due to its inherent thermal characteristics it has been thus far impossible to produce pure tungsten prints without networks of cracks and porosities forming on and underneath the surface. Many solutions have been proposed to mitigate this issue, both technological and material. In this work we are proposing novel material solution which consists of manufacturing of modified tungsten powder with spherical particle morphology. Based on well established ‘’rhenium ductile effect”, we propose Re modified W powder as the precursor for the additive manufacturing technologies. This work describes synthesis method of modified W-Re powders by means of thermal reduction and plasma spheroidization. For received powders further characteristics have been tested: physical properties, microstructure, grain homogeneity as well as chemical and phase composition. |
