| Abstract: |
Room temperature and elevated temperature tensile tests were performed on Vacuum Plasma Spray (VPS) formed tungsten and tungsten alloy samples. The tungsten alloys evaluated included tungsten-hafnium carbide (W-HfC), tungsten-rhenium (W-Re), and tungsten-rhenium-hafnium carbide (W-Re-HfC). The tungsten-hafnium carbide samples were doped with HfC additions with varied particle size of the HfC. For the tungsten rhenium alloys, the rhenium additions varied up to-5wt%.. Room temperature and elevated temperature ultimate tensile strengths and percent elongation values for the alloys will be shown. Testing to determine the ductile to brittle transition temperature was also conducted.
