However this capability is not yet available and as explained in this Section resear are still far from reaching that goal. This is the case even for simple systems such as metal pair that form solid soluti The opportunities for understanding interfacial behavior come from studies conducted at the atomic level for exan using scanning tunneling microscopy transmission electron microscopy first principles energy band calculations embedded atom potential calculations with appropriate correlations to both micromechanics and a macroscopic leve vice versa. The computational and experimental tools that begin to provide insight at these levels have only recently developed. Because the interest in interfaces is so diverse all combinations of metals ceramics semiconductors glasse conducting polymers the advances in interfacial science encompass the creative efforts of a large number of peop organizations. Thus the quantity of available literature seems overwhelming and perhaps disjointed. It will bee apparent that there is no preferred approach to the treatment of dissimilar welds or welding. It really depends o interests and objectives of each engineer. For example if you know that what you are doing actually works that is produces a joint and are searching understanding then this Section of the Handbook will guide you to the appropriate technical literature. If you hav idea and need guidance for bonding testing processing or interpreting the data then this Section should also provk direction. Lastly if the reader wants state-of-the-art research and development topics then those can be found i Section as well. This should provide the reader with a comprehensive overview of the welding of dissimilar metals. Therefore this Section is concerned with the fundamentals of welding and joining materials via the application I nonmelting process. The specific processes usually associated with this technology are also discussed. Before cons nonmelting .
