<p>A diffusion welding method is provided. The method includes at least a) obtaining metal plates, b) stacking a plurality of the plates obtained in step a) in order to obtain a stack, and c) diffusion welding applied to the stack obtained in step b) so as to obtain a set of welded plates. The plates obtained in step a) comprise a biphasic titanium alloy, and during step c), the stack is heated to an assembling temperature comprised between a minimum temperature allowing bonding between the plates of the set of welded plates on the one hand, and a maximum temperature past which the alloy becomes monophasic on the other hand, the heating of the stack having a duration shorter than the maximum duration beyond which the alloy of the plates of the set of welded plates comprises grains with a grain size index strictly lower than 6. A corresponding heat exchanger is also provided.</p> |
