Abstract Scope |
Additive manufacturing (AM) has revolutionized complex component production, including copper-tin alloy (Cu-Sn) for automotive engines, industrial equipment, power transmission, and motion control systems. However, there remains a gap in understanding their wear properties and the feasibility of controlling the as-built properties. We focused on Cu-Sn10 alloy due to its balanced strength, ductility, good wear properties, and cost-effectiveness. We discovered that the cooling rate influenced the formation, content, and shape of the delta phase, with higher cooling rates resulting in increased delta phase. Quantitative analysis confirmed the presence of nano-sized delta phase, which enhanced hardness, yield strength, and wear resistance. These findings highlight the crucial role of microstructure, specifically the nano-sized delta phase, in determining the mechanical properties of AM Cu-Sn10 alloy parts. Controlling the cooling rate offers opportunities for optimizing component properties and broadening applications. |
