SYMPOSIUM C
MATERIALS FOR HIGH TEMPERATURE APPLICATIONS

Engineering materials are frequently submitted to mechanical stresses at high temperatures for long times. Under these conditions, a material will creep and undergo a time-dependent (viscoelastic) increase in length. During the material usage or testing, apart from the increase in crystalline defects, reflected mainly in the dislocation density, there is also coarsening of the phases in the microstructure and /or formation of new ones, which may be even undesirable. Voids may also nucleate, grow and coalesce leading to crack nucleation, propagation and eventually fracture of the material. Depending on temperature and on the environment, phenomena such as oxidation, carburizing, and hot corrosion, may contribute significantly to the reduction of the life expectancy of the component. To make this situation even more critical, the demand on the maximum usage temperature of the materials has been continuously increasing in the last decades, aiming at greatest levels of machine efficiency. This symposium looks into the main aspects related to processing, microstructural characterization, assessment of properties and understanding of all kind of phenomena that are critical for the application of materials with engineering significance at high temperatures..

Scientists, engineers and students are invited to present and discuss their findings on the following topics:

• Nickel-base, cobalt-base, and iron-base superalloys;
• Refractory metals (W, Mo, Ta, and Nb) and alloys;
• Stainless and heat-resistant steels;
• Intermetallics;
• Coatings;
• Ceramic materials;
• Processing;
• Creep;
• Microstructural stability;
• Environmental effects and oxidation resistance;
• Materials for energy systems;
• Materials for petrochemical industry;
• Materials for fission and fusion nuclear reactors.
