| Abstract Scope |
Functionally graded materials (FGMs) provide improved properties for industrial uses through their gradual changes in composition or structure. Additive manufacturing (AM) is an effective method for creating FGMs, but it faces difficulties due to inadequate bonding and mixing between materials, which lead to defects and reduced properties. To address this challenge, we explore solute redistribution during the laser powder bed fusion (LPBF) process using Cu alloy powder on an Al base plate. Real-time imaging at 80 kHz reveals complex fluid dynamics in the melt pool of Cu and Al. Post-mortem quantitative tomography analysis determines the local Cu composition, offering insights into mixing behavior. The experimental findings are supported by computer simulations to achieve a comprehensive understanding of FGM development via AM. |
