Solid State Bond

In a Solid State Bond (also called thermo-compression Bond), dissimilar materials with dissimilar grain structure, e.g. molybdenum to tungsten, are joined using a very short heating time, high weld energy, and high force. There is little melting and minimum grain growth, but a definite bond and grain interface.  Thus the materials actually bond while still in the 'solid state'.  The bonded materials typically exhibit excellent shear and tensile strength, but poor peel strength.
