| Abstract Scope |
Magnetic freeze-casting is a promising technique for creating porous structures replicating the impressive mechanical properties of human bone. Doing so using Helmholtz Coils is of interest due to the highly uniform fields they generate. Though high in uniformity, Helmholtz Coils lack strength which limits their use in magnetic freeze-casting. In this work, surface-magnetized alumina platelets are added to freeze-cast slurries to enable microstructural control and increase ultimate compressive strength via the Hall Effect of scaffolds fabricated using low strength magnetic fields. Additionally, slurries are changed to alter the Hall Effect to expand this method of microstructural control. This work also looks to identify how the failure modes change in a freeze-cast scaffold as the microstructure becomes aligned and the amount of microstructure alignment that is necessary to achieve such is important. Using this knowledge more informed Helmholtz Coils setups can be designed, and magnetic freeze-casting expanded. |
