For a better understanding of both recrystallization and ductile to brittle transition temperature, tensile tests are performed on potassium doped tungsten, WVWM, up to 2000°C at different loading rates (0.2 and 42 mm/min). The mechanical properties are highly dependent on the microstructure. The etched sample surface and fracture surface after tensile testing are microstructurally assessed by Optical Microscopy (OM), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). All the obtained data will be summarized into a database that can be used for future modelling input and will be compared to the same grade material after neutron irradiation.
