Production Processes, Microstructural Properties, Heat Treatment Strategies, Mechanical and Fatigue Behavior of AlSi10Mg Alloys Produced by Additive Manufacturing Method

AlSi10Mg aluminum alloys are widely used in additive manufacturing (AM) due to their low density, high specific gravity/strength, good castability, and favorable heat properties. Laser-based powder bed fusion (LPBF) and directed energy deposition (DED) techniques are considered among the most suitable methods for producing parts with complex geometries, near-net shape, and requiring adjustable microstructure properties. This study presents a comprehensive review of high-performance AlSi10Mg alloys produced by additive manufacturing methods. The chapter covers production processes, microstructural properties, heat treatment strategies, mechanical and fatigue behavior, current challenges, and future research trends.
