Abstract:

This study presents the development of two novel AlSi7Mg-based alloys tailored for additive manufacturing applications. The research was driven by a computational modeling approach to optimize the alloy composition and predict material behavior during processing. Following the modeling phase, gas atomization was employed to produce the alloy powders, ensuring suitable characteristics for powder bed fusion additive manufacturing (PBF-AM). Specimens were fabricated via PBF-AM to assess the printability and mechanical performance of the developed alloys. Comprehensive mechanical characterization (tensile testing, hardness measurements, and microstructural analysis), was conducted to evaluate the alloys performance. Results indicate that the newly developed AlSi7Mg-based alloys demonstrate improved mechanical properties and compatibility with AM processes compared to conventional AlSi7Mg. These findings contribute to the advancement of materials engineering for additive manufacturing, offering enhanced options for lightweight and high-performance applications.UNCLASSIFIED – Based on the Foreground Information under EDA contract No B.PRJ.RT.797 covering the Ad Hoc Project entitled AMALIA
