| Abstract Scope |
Magnesium (Mg) alloys with trace additions of Strontium (Sr) and Calcium (Ca) are promising candidates as temporary implants due to their excellent biocompatibility and bioresorbability. Additionally, having a low elastic modulus close to the human bone decreases the stress shielding effect. Novel low-temperature additive manufacturing (AM) techniques (e.g., Material Extrusion) can enable the fabrication of intricate Mg components where the main limiting factor is the low sinterability of prevalent Mg alloys. This study investigates thermodynamic and kinetic aspects of Mg sintering when both solid-state and liquid-phase sintering processes are activated. The effects of sintering temperatures (kinetics), and solid-liquid interactions (thermodynamics) on Mg sinterability were evaluated. Differential scanning calorimetry was used for sintering parameter selection. Wettability analyses were also employed to investigate the high-temperature interactions and mutual solubility of liquid-solid phases during sintering. Sinterability of Mg-Sr-Ca alloys was investigated based on Archimedes principle, Image Analysis (SEM), and X-ray Computed Tomography techniques. |
