Solid-state bonding of iron-based alloys, steel–brass, and aluminum alloys

Abstract Many genuine solid-state-bonding experiments have been performed using a wide range of metals; the latter includes superplastic ultra-high-carbon steel, Fe–Ni–Si alloy, manganese steel, brass, stainless steel, iron-silicon alloy as well as superplastic aluminum alloys 5083 and 7475. The roll-bonding process was employed to study the ability to mechanically bond (one kind of solid-state bond) iron-based alloys at intermediate temperatures. Press bonding was meant to determine the effect of three interconnecting factors—temperature, time, and deformation—on the strength of the diffusion bond. The results and analysis conclude that diffusion bonding is difficult to achieve without successful mechanical bonding preceding it.
