The fracture behavior of several tungsten based alloys was characterized by standard Charpy tests which have been performed up to 1100°C in vacuum. Due to their fabrication history (powder mixing, pressing, sintering, rolling) all materials had specific micro-structures which led to typical delamination fractures. The influence of notch machining method was also investigated. All results are discussed and assessed with respect to the optimization of future divertor component fabrication.
