Linking Powder Properties, Printing Parameters, Post-Processing Methods, and Fatigue Properties in Additive Manufacturing of AlSi10Mg

Additive manufacturing (AM) of metals can be broadly accomplished via two defined technologies: powder bed fusion and directed energy deposition. During AM fabrication, the melted feedstock material experiences fast thermal cycling due to layer-by-layer deposition process resulting in microstructures properties that are drastically different from traditionally manufactured parts. For become a viable for fabricating critical components made high-performance structural alloys, such as AlSi10Mg, comprehensive understanding is required toward developing process-structure-property relationships prevalent AM. with its good castability, strength, hardness, dynamic properties, typically used fabricate withstand high loads. This alloy has been consolidated predominantly by laser (L-PBF) method several mechanical fatigue, have reported date. article, first, summarizes as-deposited heat-treated AlSi10Mg specimens fabricated L-PBF. Then, article discusses linkages among printing parameters, specimen geometry, post-processing techniques, fatigue properties. discussion followed section on life prediction using computational modeling. Finally, identifies research gaps pinpoints future opportunities.
