Abstract

In this work, Al-5 Mg-0.1Ti and Al-5 Mg-0.1Ti-0.2Sc-0.1Zr (wt.%) alloys fabricated by cold metal transfer (CMT) and electron beam additive manufacturing (EBAM) are investigated. The Sc and Zr addition improves the processability of Al–Mg-Ti alloys by eliminating cracks in their as-deposited microstructure. Additionally, the Sc and Zr addition promotes columnar to equiaxed transition in the as-deposited Al–Mg-Ti alloys, exhibiting a fully equiaxed microstructure with grain sizes decreased by at least 70% compared to the unmodified alloys in both cases. Grain refinement in the as-deposited Al–Mg-Ti-Sc-Zr alloy samples is attributable to the inoculation effect of primary Al₃(Sc, Zr, Ti) phase and Zener pinning effect of the solid-state precipitates of Al₃Sc. Moreover, the Sc and Zr addition improves the hardness of Al–Mg-Ti alloys in the as-deposited state, achieved by grain size strengthening and precipitate strengthening.
