This work has been carried out to investigate, by means of neutron strain scanning, the stress field in brazed samples of interest for the construction of plasma-facing components, such as the 'divertor', in future fusion reactors. The investigated samples were obtained by brazing with different procedures a tungsten and a Glidcop (copper alloy) platelet. The experimentally determined evolution of the internal stress field between room temperature and 500°C appears critically dependent on the brazing conditions, which must be taken into account in the design of real-scale components.
