Design of high-performance sustainable aluminum alloy series for laser additive manufacturing.

ABSTRACT: Lightweight Al alloys with enhanced mechanical properties are essential for structural applications across various industries. To promote sustainable material flow, this study introduces an Al-Fe-based multi-elemental alloy series optimized for laser-based additive manufacturing (AM) using powder bed fusion (PBF-LB), leveraging recycling-friendly Al alloys with Fe as a major impurity. The alloy design is based on the concept of elemental partitioning into either the liquid phase (forming metastable Al₆Fe phase for strengthening) or the solid phase (α-Al matrix) during solidification. Investigations of PBF-LB processed Al-Fe-X ternary alloys (X: Cu, Mn, and Ti) reveal the distinct roles of these alloying elements: Cu and Mn stabilize the Al₆Fe phase, while Ti enhances
