| Abstract Scope |
Additive Manufacturing (AM) has evolved from a prototyping tool to a viable method for producing final products with complex geometries. This advancement is largely driven by laser beam powder bed fusion techniques, which use micrometre-size metal powders. The choice of powder significantly influences the density, surface roughness, and microstructural properties of the final parts. Despite these insights, there is limited understanding of the complex interplay between powder properties, microstructure, and mechanical properties in AM processes. The motivation for this research stems from examining powder characteristics that result in unique microstructures and mechanical properties, which vary considerably among as-built samples. In this study, the Cu-10Sn metal powders from three suppliers were used to fabricate bulk samples. Tensile tests were carried out on three as-built samples, revealing unique properties for each. Furthermore, through using microscopy techniques, we correlate the powder characteristics-microstructure-mechanical property relationships toward developing advanced copper alloys with excellent mechanical properties. |
