Abstract:
Magnesium AZ-alloys are the work horse for many ultra-light-weight aerospace, automotive and consumer applications. Novel research introduces Mg-alloys also into binder based processing techniques, such as Metal Injection Moulding for economic near net shape mass production as well as 3D-printing for individual prototyping of complex shaped parts, even with hollow structures inside of a dense shell. This study handles two questions:How can the chosen AZ41-alloy exhibit maximum material properties and reproducibility using MIM? In addition, how can the 3D-printing processing be refined to come as close as possible to MIM? In order to answer these questions, several approaches in view of the used powder quality, particle distribution size as well as furnace and printing parameters were performed. Maximum ultimate-tensile-strength (UTS) of 226 ±7.1 MPa at 10.8 ± 2.1% elongation at fracture can be achieved using MIM. The 3D-printing approach could come close up to 89.5% of the MIM result.
