| Abstract Scope |
The material with far from equilibrium (FFE) state may exhibit extraordinaire functional properties. Obtaining FFE bulk materials through powder consolidation approaches requires the specifically designed powder synthesis method for the particular consolidation method. This is because an appropriate energy balance (heat) is required to obtain bulk form while maintaining FFE state. In other word, FFE materials can be obtained only within the specific processing condition (processing window). When FFE materials are overheated, it will convert to an equilibrium state with conventional properties. Here we will present results on the chemical synthesis of metastable material/phases, and the integration into a consolidated nanocomposite via Current Activated Pressure Assisted Densification (CAPAD). We will show the processing of metastable iron oxide/silica hard bulk magnets with coercive fields comparable to typical rare-earth magnets. And an increase in energy product of ferrite magnet by forming nano-composite with 3d transition metal will be presented. |
