Tailoring mechanical properties of AlSi9Cu3(Fe) alloy via heat treatments in PBF-LB Processing

Year: 2025

Type: article

Abstract: • Heat treatments tailor the mechanical properties of PBF-LB AlSi9Cu3(Fe) alloy. • Analyses reveal phases and microstructure evolution after heat treatment. • As-built AlSi9Cu3(Fe) shows the highest strength but poor ductility. • Direct ageing enhances hardness but leads to reduced toughness. • High-temperature annealing dissolves the Si network, maximising ductility.
