A MAGNETICALLY CONTROLLED CASTING PROCESS FOR MULTISTRUCTURAL MATERIALS

Current casting methods that produce features in a solid material with rapid prototyping techniques require highly specialized and expensive equipment. These techniques in addition to being time consuming can also result in heterogeneities and reduction in performance. UCR research team led by Professor David Kisailus has developed an exciting one-step casting process that produces solid materials displaying controlled structural ordering into a wide range of sizes and shapes. The casting process utilizes a liquid material that is placed in a magnetic field and the liquid material solidifies over a ferrofluid resin/metal interface. The magnetic field allows for the ferrofluid to produce predictable and controllable patterns into the liquid material. The range of patterns generated includes honeycombs, labyrinths, spikes, ridges, and concentric rings. Venkata Krishnamurty venkatak@ucr.edu (951) 827-4967
