Abstract

MIM-technique possesses high potential for the SF6 free near net shape mass production of small sized and complex shaped parts. Furthermore, MIM involves a high degree of freedom regarding individual alloy- and MMC-composition using the blended elemental (BE-route). Resent research has highlighted MIM of Mg-alloys as highly suitable for biomedical applications like screws, nails and bone-plates, as well as for commercial 3C applications. For prototyping and low quantities, the feedstock can be used for 3D-filament print, too. Hence, demonstrator parts and test specimen could be produced very successfully, ready for industrial upscaling. Increased mechanical properties of MIM dogbone tensile test specimen could be achieved using Mg-2.6Nd-1.3Gd-0.5Zr-0.3Zn alloy (EZK400, UTS: 164 MPa, YS: 123 MPa, \( \upvarepsilon_{\text{f}} \): 3.4%) and AZ81-alloy for commercial applications (UTS: 240 MPa, YS: 118 MPa, \( \upvarepsilon_{\text{f}} \): 4%). Thus, the mechanical properties are currently equivalent to those of as cast material and obtaining high development potential.
