| Abstract Scope |
Tungsten has a wide range of uses thanks to its high melting point and hardness. Often in literature, it is rare to find data about crack-free tungsten specimens and their manufacturing process. This project aims to study the effects on the microstructure of crack-free tungsten manufactured with Electron Beam Melting after going through three different Hot Isostatic Pressure cycles, performed at constant pressure and different temperatures. This evaluation was performed in terms of how grain size and defect content are affected when being exposed to three different HIP cycles. Furthermore, all specimens were manufactured using the same parameters and in the same batch. Upon optical microscopy, specimens showed a higher amount of defect formation which may be attributed to temperature variation between specimen formation, leading to unsuccessful melting of some tungsten particles. A comparative analysis of the micrographs obtained is performed to determine the effect of the Hot Isostatic Pressure. |
