Abstract
The case of welding samples of titanium aluminide through nanostructured Ti/Al interlayer was used to calculate stresses arising in the surface layers of welded intermetallide samples, initiated by intensive heat evolution at running of the reaction of self-propagating high-temperature synthesis in the interlayer.
