Effect of the primary heat treatment on the bond formation in coldwelding of aluminum and steel by cold forging.
In: Journal of Materials Processing Technology, 214, pp. 2040-2048. [Article]
Abstract
Cold forging enables the manufacturing of high strength monolithic components. When used as joiningtechnology it can also be extended to an enabler of multi-material product design. The contact conditionsat the interface between the components during the cold forging process play a crucial role. The joining oftwo billets of steel and aluminum is investigated by a finite element analysis with regard to the materialdistribution and the effect of a primary heat treatment of both materials. These parameters affect thesurface enlargement and the contact normal stress which are decisive parameters for the formation of asound bond between aluminum and the hardly cold weldable steel. The experimental results present theeffect of a primary heat treatment on the bond formation. Microscopic analyses of the bond formationallow a deeper insight into the bonding mechanism. Thus, the results lead to process design guidelinesfor cold welding by cold forging.
