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

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.
