Abstract Scope |
Zn-4Al alloy, commonly known as Zamak 3, has remarkable fluidity that distinguishes it among all cast alloys, making it exceptionally suitable for die casting of complex structures. However, there is always a demand to improve its fluidity further so that it can be used to produce thinner, more complex, and more ductile components in the medical and electronic industries. Traditional heat treatment improves ductility but often reduces strength. This study explores using emerging nano-treating technology to enhance the fluidity and properties of Zn-4Al alloy. Adding 0.5 vol% of dispersed nanoparticles into the melt of Zn-4Al enhanced its fluidity by over 30% and improved ductility from 9% to 54%. Nanoparticles facilitate a refined microstructure by enhancing nucleation, restricting dendritic growth in both primary and secondary phases, and a more gradual solidification process, resulting in improved ductility and fluidity. This study demonstrates the significant benefits of nano-treating Zn alloys for broader applications. |
