| Abstract Scope |
Manufacturing processes yielding stronger, yet light-weight structures are valuable in many industries and scientific application. Freeze casting is a fabrication process that offers a way to achieve these strong, light-weight structures, but only in a single direction (the direction of the templating ice growth). Applying a uniform magnetic field to these structures allows one to achieve increased strength in an additional direction. A Helmholtz coil along with a permanent magnet setup were used to apply weak, uniform fields in an oscillating mode (i.e., a stronger magnetic field in a single direction with a weaker oscillating field in an orthogonal direction) and a non-oscillating mode (i.e., magnetic field applied in a single direction). These oscillating magnetic fields led to more organized and stronger freeze-cast materials, compared to freeze cast materials with no oscillating magnetic field. These stronger, light weight structures could lead to better, higher performing manufactured materials. |
