The other of the body of polycrystalline diamond material or the substrate is then placed on the layer and the body of polycrystalline material, the layer and the substrate are then subjected to a predetermined temperature at least equal to or greater than the melting point of the eutectic mixture at substantially ambient pressure or a vacuum to melt the metal in the binder phase at the interface with the substrate so that the metal from the binder phase infiltrates into the adjacent body of polycrystalline diamond material to form a bond between the body of polycrystalline diamond material and the substrate..
