Abstract Scope |
Magnesium (Mg) alloys are of interest for use in biodegradable load-bearing bone implants due to their excellent biocompatibility, comparable mechanical properties to natural bone, and unique ability to naturally degrade in the physiological environment. Over past decade, additive manufacturing of Mg alloys has gained increased interest for the potential to fabricate complex geometries for extreme light-weighting or improved functionality. Nevertheless, there is still a significant need to establish the influence of various processing parameters on the microstructure and mechanical behavior of additively manufactured Mg alloys. In this study, the effect of processing parameters (i.e. laser power and time interval) on the microstructure, mechanical, and degradation behavior of WE43 Mg alloy specimens fabricated by laser powder directed energy deposition (LPDED) was investigated. Microstructure characterization of the additively manufactured samples was conducted using optical microscopy and scanning electron microscopy. Mechanical behavior of the samples was investigated using microhardness and uniaxial tensile testing. |
