Influences of deposition current and interpass temperature to the Fe3Al-based iron aluminide fabricated using wire-arc additive manufacturing process

Journal Article


Abstract


  • This research presents an innovative wire-arc additive manufacturing process for fabricating Fe3Al-based iron aluminide buildup walls with 30 at.% Al content. The alloy is produced in situ through controlled addition of the elemental iron and aluminum components into the welding process. The influences of major process parameters, including deposition current and interpass temperature to the material and mechanical properties of the buildup walls are investigated using optical microstructure analysis, hardness testing, tensile testing, X-ray diffraction phase characterization, and electron dispersive spectroscopy. The results have indicated that deposition current is the dominant factor to the grain size in the buildup walls, and interpass temperature is critical for preventing stress induced cracking.
