International Symposium on Ceramic Matrix Composites
Monolithic ceramics are brittle and show catastrophic failure. In contrast, ceramic composites are strong, tough, and exhibit graceful failure under loading. These composites show promise for many advanced engineering applications at elevated temperatures. This symposium will cover various aspects of ceramic composites, including the latest developments.

Topics:

• Oxide, nonoxide, carbon/carbon, glass and glass-ceramic composites
• In situ and nanocomposites
• Fiber, whisker and particulate reinforcements
• Composite interfaces and interface coatings
• Processing, fabrication and characterization
• Mechanical properties at room- and elevated-temperatures
• Modeling, design and applications
• Environmental effects, test methods, NDE and joining methods

Organizer: Jitendra Singh, Air Force Office of Scientific Research; Co-organizers: N.P. Bansal, NASA Glenn Research Center; K. Niihara, Nagaoka University of Technology; A.R. Boccaccini, Imperial College of Science, Technology & Medicine

Micro-Manufacturing: Material Behavior, Deformation Mechanics, Process Control and Applications
There is a need to further integrate and miniaturize metallic components in the highly integrated and compact devices in today's applications. Various studies responded to this need by scaling down the existing manufacturing methods to achieve cost effective and robust micro-parts and/or micro-features.  However, there are remaining questions regarding the understanding and modeling of the material response at micro-scales. Furthermore, other issues such as deformation mechanics, tribological interactions, process control, etc. also need further characterization and in-depth understanding.  Machines and systems, metrology, material handling, etc. topics are few more that can be added to this list. In this symposium, we invite papers discussing the above issues individually/in combination either for certain product applications or from the point of view of the basic sciences and understanding purposes.

Topics:

• Micro-forming, -molding, -machining and applications
• Metrology
• Material behavior
• Tribology
• Deformation mechanics
• Process control, modeling and optimization
• Machinery, automation and system level issues

Paradigm Shift in the Metals Industry
The metal industry is going through a revival where traditional metals are pressed to meet new performance targets, with higher quality, at lower cost, with new application requirements, and globally sourced. As a result, the industry is stepping up to meet these and other new targets through implementation of new alloys, process improvements, quality goals and systems, and plant improvements at an ever increasing pace. Globalization is also creating new opportunities for geographical growth and collaborations. An overview of these activities will be presented by each industry segment, namely aluminum, copper/brass, magnesium, steels, superalloys, refractory metals, and precious metals. Although bulk of the presentations are by invitation, interesting and thought provoking topics will be considered for the symposium. Prospective speakers are encouraged to submit the abstracts for inclusion in the symposium.

Topics:

• Aluminum
• Copper/brass
• Magnesium
• Steels
• Superalloys
• Refractory metals
• Precious metals

Processing, Properties and Performance of Composite Materials
The symposium will focus on recent advancements in the area of metal- and polymer-matrix composite materials. The primary focus of this forum is to trace the path from the laboratory to the marketplace for advanced composites. All types of composite materials including in situ, green and bio composites are within the scope of the symposium. Physical, mechanical, electrical and special properties of composites can be reported. Matrix-reinforcement interface and interpenetrating phase composites will be of special interest in the case of in situ composites. The symposium is intended to provide researchers and industry a platform to share recent advances in processing, structure-property relations and modeling capabilities to enable development of new applications. The symposium will include invited and contributed presentations. Full text papers are eligible to appear in the collected proceedings of the conference, and the organizers are presently pursuing publication of a print volume.

Topics:

• Processing and properties of metal and polymer matrix composites
• Modeling and simulations in composite materials
• Applications of advanced composites
