Electric Field Enhanced Processing of Advanced Materials II: Complexities and Opportunities Conference
Abstract
The Electric Field Enhanced Processing of Advanced Materials is the second international conference in the area of the fundamental science that underlies electromagnetic field driven sintering processes (Spark Plasma (SPS), Microwave Assisted, and Electric Field Flash Sintering) that enable time and cost efficient processing of bulk ceramics material. This conference provides a forum for the presentation of high-quality, original research covering various aspects of these structural and energy conversion material systems, where innovations in the field - theoretical and experimental ~ will be presented. This symposium will bring together experts in solid mechanics, engineering, materials science, chemistry and physics to explore recent breakthroughs and emerging opportunities to efficiently develop novel ceramic based systems with superior properties through the use of electrical and electromagnetic fields which influence the generation and the movement of defects and control mass transport in ionic ceramics. The convergence of research from SPS, microwave sintering, flash sintering and underlying electro-chemomechanical phenomena has provided the opportunity to develop a scientific community in this area. The first international meeting (also supported by ONR and ONRG) brought researchers together from around the world and provided the initial opportunity for a fundamental understanding of the scientific mechanisms and formulations for field induced effects in ceramics at the molecular level. This resulted in a new ONR33 BRC initiative in this area. Significant advances have been made over the past three years. But there are still unresolved scientific issues that prevent the community from overcoming technical challenges in reliability and reproducibility of properties ~ and hence, the inability to insert this technology into operation. Nonetheless, the field assisted sintering community is growing in no small part because of the advances in scale-up and the ability to reduce sintering time from >24 hrs to minutes. The goal of the meeting is to provide a forum for the sharing of ideas, and to enhance communication among this diverse group of technical experts, thereby contributing to the acceleration of future advances in the field. Topics to be addressed by this conference include: (i) Latest results in field assisted processing (eg hybrid techniques, phase transformations, application of field assisted sintering to complex ceramic oxides for lithium oxide battery applications) (ii) Fundamental mechanisms shared by SPS, Microwave Sintering and Flash Sintering, (iii) In-situ experimental techniques, (iv) Influence of field assisted processing on properties of materials, (v) Ab-initio and molecular dynamics modeling, and (vi) Synthesis and integration for rapid manufacturing-scienceThis meeting provides a single venue to review technical progress of this international research community and provide guidance to the NRE, particularly ONR 33, but also ONR 30 and 35, of the developments in the area of structural material mechanics, and energy conversion systems and its use for producing ceramic materials and structure much more quickly and cheaply than can currently be done for implementation in advanced platforms and weapon systems with superior performance to current systems using materials that have the required strength, but are lighter, and have greater endurance in harsh environment than those currently available. This area supports the Amphibious and Expeditionary Maneuver; Mission Capable, Persistent, and Survivable Sea Platforms; and Aviation, Force Projection, and Integrated Defense S&T Focus Areas; and the Assured C3, Battlespace Awareness & Integrated Fires, Sea Control, and Power Projection CNOG Priorities.
