Abstract: A joint between two metallic materials obtainable by carrying out a process comprising the steps of: providing two metal members (12,14) and a prealloyed interlayer foil (16); creating a joint interface by positioning said foil (16) between said members (12,14); applying a load transverse to said joint interface. Said process further comprises a step of applying localized, rapid heating in the area of said joint interface at a temperature which effects bonding of said members (12,14) while causing no degradation of microstructural or mechanical properties of the metal and a coarsening of grains in rim portions of said members (12,14) so as to form creep resistant rim portions.
