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.

[ What is claimed is:] [1.] A process for joining two metallic materials together comprising the steps of:providing two parent metal members to be joined and a prealloyed interlayer foil having a composition which includes a melting point depressant;creating a joint interface by positioning said interlayer foil between two spaced apart surfaces of said two parent metal members to be joined together;applying a load substantially transverse to said joint interface so as not to cause deformation of said surfaces; andcreating a creep resistant, damage tolerant material at rim portions of the parent metal members by applying localized, rapid heating in the area of said joint interface for a time of 1 to 2 hours at a temperature which effects bonding of said two parent metal members while causing a coarsening of grains in rim portions of said metal members so as to form creep resistant rim portions.
