Abstract
The present invention relates to a process for joining two metal members together. The process comprises the steps of providing two parent metal members to be joined and a prealloyed interlayer foil having a melting point depressant; creating a joint interface by positioning the foil between two spaced apart surfaces of the two parent metal members to be joined together; applying a load substantially transverse to the joint interface which does not cause deformation of the surfaces; and applying localized rapid heating in the area of the joint interface at a temperature sufficient to effect bonding of the two metallic members while causing little or no degradation of microstructural or mechanical properties of the parent metal and a coarsening of grain size in rim portions of the metal members.
