Abstract:

Here, we report the leading manufacture of the large-scale integral weldless stainless steel forging ring (φ = 15.6 m) by the multilayer additive hot-compression bonding technology. Moreover, the detailed interface healing mechanism involving interfacial oxide evolution is elucidated, which validates the feasibility and reliability of the technique we proposed.

Key words: The largest stainless steel forging ring, Interface bonding, Interfacial oxides, Multilayer additive hot-compression bonding
