A method of joining an aluminum workpiece and an adjacent overlapping steel workpiece by reaction metallurgical joining, and the resultant metallurgical joint formed between the two workpieces, are disclosed. The method involves compressing a reaction material located between the aluminum and steel workpieces and heating the reaction material momentarily to form a metallurgical joint that comprises bonding interface between the reaction material and the steel workpiece and a bonding interface between the reaction material and the aluminum workpiece. The reaction material is formulated to be able to interact with both aluminum and steel in order to establish the bonding interfaces of the metallurgical joint. Moreover, the practice of oscillating wire arc welding may be employed to deposit the reaction material in the form of a reaction material deposit onto the steel workpiece prior to assembling the steel and aluminum workpieces in a workpiece stack-up.
