| Abstract Scope |
Welding aluminum with copper-based alloys to create functionally graded materials (FGMs) presents several challenges due to the distinct physical, chemical, and mechanical properties of aluminum and copper. These challenges include differences in melting temperature, thermal expansion coefficient, thermal conductivity, formation of intermetallic compounds, and increased residual stresses. Wire arc additive manufacturing (WAAM) technology is a promising technique capable of addressing these challenges. This study investigates the challenges associated with the deposition of aluminum-copper bimetallic FGMs using WAAM. The integrity of the deposited walls is evaluated under different processing parameters and preheating temperatures, with particular attention to the interface between the two dissimilar materials. Temperature variations during the manufacturing process are continuously monitored using thermal imaging. The microstructure, intermetallic compounds, elemental and porosity volume fraction distribution along the building direction are characterized using optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, x-ray diffraction, and micro-hardness measurements. |
