Mechanoelectrically Activated Synthesis of Dense, Bulk Nanostructured, Complex Crystalline and Glassy Hard Materials

摘要

The broad objective of the completed work was to investigate the effect of mechanical and electric field activation on the synthesis and properties of materials, with special emphasis on nanostructured hard materials. We have investigated several aspects of this, including: (a) Synthesis and Microstructural Evolution under Field Application, (b) Synthesis of Bulk Nanostructured Materials by Mechanical and Field Activation, (c) Investigations on FGM Formation and Properties, (d) Investigations on the Field Activated Synthesis Complex and Hard Materials, (e) Modeling Studies, (f) Microalloying, (g) Field Activated Consolidation and Crystallization of Bulk Metallic Glasses, and (h) Synthesis of Ultra-Hard Boride Phases. Brief descriptions of the accomplishments in each of these thrusts are provided, with details given in the cited publications listed at the end of this report.
