Abstract:

Bioresorbable magnesium (Mg) alloys have been receiving increased attention as an emerging class of biomedical metallic materials due to their high biocompatibility. The potential use of additive manufacturing (AM) for biomedical Mg-based alloys will allow the processing of bioresorbable patient-specific implants. However, the low sinterability of Mg-based alloys is a key issue limiting the efficiency of post-processing required for the low-temperature AM techniques (i.e., extrusion-based techniques). This study aims to fundamentally evaluate the sinterability of the alloys based on Mg-Sr-Ca system designed via thermodynamic calculations. Powder metallurgical route with in-house powder processing was applied and final porosity levels were determined to assess sinterability where thermodynamic calculations along with the differential scanning calorimetry (DSC) were used to select the sintering parameters.
