Title: An Attractive Materials Process: Exploring High Magnetic Field Processing for Developing Customized Microstructures with Enhanced Performance

Abstract

Multiple facets of an innovative research endeavor involving high magnetic field processing will be highlighted for this very promising technology initiative for materials and process development. This approach has both scientific and industrial relevance with significant energy savings and environmental benefit ramifications and represents a major step towards achieving materials by design goals for the next generation of materials encompassing both structural and functional material applications. Our experimental and modeling research efforts are clearly demonstrating that phase stability (conventional phase diagrams) can be dramatically altered through the application of an ultrahigh magnetic field. This ability to selectively control microstructural stability and alter transformation kinetics through appropriate selection of the magnetic field strength is being shown to provide a very robust mechanism to develop and tailor enhanced microstructures (even potential bulk nanostructures through accelerated product phase nucleation and transformation kinetics) with potentially superior properties. The broad goals for this research are to demonstrate and document the influence of ultrahigh magnetic field processing on the phase equilibria and kinetics for ferromagnetic and paramagnetic material systems and to develop predictive capability based on first principle calculations.

  • Thermodynamic calculations based on Gibbs free energy in the magnetization-magnetic intensity-temperature (M-H-T) magnetic equation of state space demonstrate that significantly different phase equilibria may result for those material systems where the product and parent phases exhibit different magnetization responses. These calculations show that the Gibbs free energy is changed by a factor equal to -MdH, where M and H are the magnetization and applied field strength, respectively. Magnetic field processing is directly applicable to a multitude of alloys and compounds for dramatically influencing phase stability and phase transformations. This ability to selectively control microstructural stability and alter transformation kinetics throughmore » appropriate selection of the magnetic field strength promises to provide a very robust mechanism for developing and tailoring enhanced microstructures (and even nanostructures through accelerated kinetics) with superior properties for a broad spectrum of material applications. For this Industrial Materials for the Future (IMF) Advanced Materials for the Future project, ferrous alloys were studied initially since this alloy family exhibits ferromagnetism over part of its temperature range of stability and therefore would demonstrate the maximum impact of this novel processing mechanism. Additionally, with these ferrous alloys, the high-temperature parent phase, austenite, exhibits a significantly different magnetization response from the potential product phases, ferrite plus carbide or martensite; and therefore, the solid-state transformation behavior of these alloys will be dramatically influenced by the presence of ultrahigh magnetic fields. Finally, a thermodynamic calculation capability (within ThermoCalc for example) was developed during this project to enable parametric studies to be performed to predict the magnitude of the influence of magnetic processing variables on the phase stability (phase diagrams) in ferromagnetic materials of relevance to the Industries of the Future (IOF).« less
  • Prospects are discussed for accelerating the fusion reactor program, specifically that engineers must show a systematic progress along the path to fusion power, that there must be a clear indication that they are intending to develop a commercial product, and that there must be in this country, a level of total R and D on energy technology that is commensurate with the energy problem that faces the United States in the future. Certain laboratory studies are cited. Selected areas of magentic fusion reactor improvement in the last decade, and the characteristics of attractive fusion reactors are discussed. Reactor design andmore » fusion program costs are also examined.« less
  • Comments are made pertaining to a generic magnetic fusion reactor study carried out at ORNL. A second study was made of the required reactor characteristics for attractive fusion reactors. The study concluded that both the physics and economics would be achievable with present magnetic configurations.

  • A new software package is described for 2-Dimensional modelling of microwave heating. It is particularly suited to the high temperature heating of ceramics, where electrical and thermal properties are strongly dependent on temperature. The described program, x{_}tlm, runs under X-windows, which allows a microwave cavity and its contents to be entered graphically and stored as a schematic diagram. The diagram is automatically converted into a mesh format for simulation using a topology independent Transmission Line Modelling formulation. Temperature dependencies of material properties are specified as polynomial functions of temperature. Surface heat loss by the radiation mechanism, which dominates at highermore » temperatures, is also introduced into the model.« less
