Abstract

This contribution presents the first results of a study, performed by neutron diffraction, on the internal stresses remaining after brazing at 860°C in graphite/molybdenum samples developed for NET/ITER. Samples of polycrystalline graphite and a carbon-fiber composite are considered. The deformation field is characterized close to the brazing interface, within a linear spatial resolution of approximately 2 mm. The results are discussed with reference to those obtainable by other methods and to theoretical considerations. © 1994.
