This study developed a design methodology against liquid-state cracking by combining the Scheil–Gulliver solidification simulations and Machine Learning analysis to design alloys for Fusion Additive Manufacturing. Applying this design approach resulted in a Fe–20Cr–7Al–4Mo–3Ni. The alloy was successfully printed with relative densities of over 99%. Microstructure of printed material was extensively characterised through scanning and transmission electron microscopy

energy dispersive spectroscopy and x-ray diffraction

confirming a single-phase material with low texture and negligible chemical segregation. Neither solidification nor liquation cracks were detected

supporting the validity of the methodology

however

the alloy suffered from solid-state cracking

hindering the ductility.
