<p>1. A joining material for assembling components by glue-bonding, comprising a dispersion of gadolinium in an adhesive or resin with one or more constituents, the said dispersion permitting possible sub-millimetric defects of assembling to be detected by neutron-radiography, characterised in that the gadolinium either under the form of pure element or under the form of a compound or an alloy, has a grain size equal or less than that corresponds to 1000 MESH, the content of pure gadolinium being approximately between 0.5 and 7.5% by weight, referred to the weight of the joining material.</p> |
