METHOD OF JOINING DISSIMILAR METAL COMPONENTS

摘要

A process for joining high strength metal components (1,2) by electromagnetic forming techniques. One of the metal coponents (1) carries high loads or is subjected to combined stresses and strains, thus requiring that it be relatively strong and ductile. EMF or MPW processes are used to join the components (1,2), the strength of which is temporarily diminished prior to the joining step. The high strength material is subjected to a retrogressive heating and quenching process along a joined boundary thereof (3); then electromagnetically joined; and threafter, the strength of the diminished material is restored to its higher temper and strength.
