Measurement of Fracture Toughness of Pure Tungsten Using a Small-Sized Compact Tension Specimen

The evaluation of fracture toughness of pure tungsten is essential for the structural integrity analysis in a fusion reactor. Therefore, the accurate quantification of fracture toughness of tungsten alloys is needed. However, due to the inherent brittleness of tungsten, it is difficult to introduce...
