| Abstract Scope |
This study investigated the offline roll bonding of a multi-layered aluminium alloy clad designed for folded tubestock in heat exchangers. Custom core alloys and one clad alloy were cast at Innoval, followed by thermomechanical processing at Mintek, to achieve the desired final thickness contribution of the layers. Precise surface preparation was essential to ensure effective interfacial bonding without welding. The layers were assembled and roll bonded offline using a process informed by previous experiments and guidance from Innoval. A target thickness reduction of 54% was set, resulting in a complete bond at the interfaces and an actual reduction of approximately 45%. Microstructural and mechanical analyses confirmed successful bonding, supporting optimal alloy selection. This research underscores the significance of pilot-scale simulations in the new alloy development. |
