About this Symposium
Meeting Materials Science & Technology 2018
Symposium Ultra High Performance Metallic Systems for Aerospace, Defense, and Automotive Applications
Sponsorship The Metallurgy and Materials Society of CIM

Scope This symposium focuses on the research and development of novel metallic materials that show potential for significant improvements in application target properties vs. commercially available materials. Typically, ultra high performance refers to at least 50% improvement in properties of interest when compared to the current state of the art. However, research and development efforts working towards this goal will also be considered. Target properties include: room/elevated/cryogenic temperature strength; fracture toughness; fatigue strength; creep strength, corrosion resistance; resistance to tribological and environmentally assisted damage; thermal stability; weldability; formability; machinability, thermal/electrical conductivity, thermal expansion, density, etc. Ideally, presentations in this symposium will discuss implementation and transition challenges, teaming opportunities, and cost or scale-up barriers and potential solutions. Multifunctional material solutions are specifically encouraged. Proposed session topics include, but are not limited to the following metallic material systems that show promise of ultra high performance:
• Ultrafine-grained and Nanostructured
• High Entropy
• Composite/Hybrid/Graded
• High Thermal Stability
• High Temperature
• High Weldability/Formability/Machinability
• Structural Bulk Metallic Glass
• Structural Shape Memory
• Advanced Coatings and Surface Modification
