Abstract
fundamental bonding processes that occur between two metals over an explosive weld interface are described. As a physical model for interfacial bonding, Miedema’s model for alloy formation is employed, 14, 15 generalized from interatomic to macroscopic interfaces. Formation energies for metal-to-metal interfaces are calculated for a large number of metal combinations. The theoretical bond strengths, together with weldability factors, are compared with practical experience for a number of metal combinations, yielding a relatively good agreement. Other interface phenomena such as interface alloying and segregation are also treated by the present model, and for the metal systems studied, theory and experimental results were found to agree well.
