| Abstract Scope |
The cladding sheet and fin material made from two different aluminium alloys are used in radiators, heat exchangers, air cooler, evaporators, condensers, and humidifiers. The conventional manufacturing process used to produce multi-metal composites is through clad rolling, friction welding, hydrostatic extrusion, compound extrusion, and spray coating. The limitations of the existing process are upstream surface treatment, controlled rolling, post-process operations, and high rejection rate due to undesirable metallurgical properties at the clad interface. Therefore, the objective of this investigation is to develop a laboratory-scale AA3003/AA4045 compound casting slab (300mmx120mmx100mm) through the compound casting process using experimental design and simulation. The properties such as depth of dissolution, interface micro hardness, distribution of Mn, Si at the diffusion layer and microstructure of the newly developed laboratory scale compound casting slab are benchmarked with the existing literature data. |
