Title: METHOD OF SOLID STATE WELDING

Abstract

An improved method is described for pressure bonding of dissimilar metals, particularly nickel and aluminum. Using ordinary techniques for the pressure bonding of these metals, an alloy zone is usually formed between the metals, and this alloy zone exhibits undesirable brittleness and lack of tensile strengh. Formation of this alloy zone can be inhibited or prevented by heating the metals being bonded to a temperature below the melting point of either of the metals and using very high pressures for short periods of time. In this manner a bond is formed without the formation of the undesirable alloy zone.
