Abstract Scope |
Metal-AM processes involve inherent thermal transients and phase transformations during processing that can lead to cracking, print failure, and variation in mechanical properties. These areas have been minimally explored for liquid metal jetting (LMJ) based-AM, which requires only raw ingot and involves different thermal processing characteristics in comparison to other metal-AM methods. Bronze alloys based on Cu-Al-Fe parent alloy system exhibit several solid-state phase transformations from the molten state down to room temperature, which makes them an interesting candidate for study via LMJ. We present results of printing studies where bronze alloy C954 (Cu-Al-Fe) is jetted onto metallic substrates at various processing parameters. High-magnification imaging, analysis, and characterization of the printed material demonstrates the vast differences in microstructure and processing characteristics at various input processing parameters, leading to a better understanding of the properties of these materials when processed via LMJ.
