SYMPOSIUM B
Materials for high-temperature applications

High temperature materials provide the basis for many technology areas, including energy generation, chemical processing, metallurgy, and aerospace industries. These materials are usually submitted to mechanical stresses at high temperatures for long times. Under these conditions, materials do creep and undergo a time-dependent (viscoelastic) increase in length. During operation or testing, besides the increase in the amount of crystalline defects, in particular the dislocation density, coarsening of phases and eventual formation of new ones also occur in microstructure. Voids may also nucleate, grow and coalesce leading to crack nucleation, propagation and eventually fracture of the material. Depending on temperature and environment conditions, diffusion-assisted phenomena such as oxidation, carburization, and hot corrosion, may contribute to shorten the component’s life expectancy. To make this scenario even more critical, the needs for higher maximum operation temperatures have been continuously increased in the last decades.

This symposium looks into the main aspects related to processing, microstructural characterization, assessment of properties, and understanding of all 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 and refractory materials;
High-temperature processing;
Creep;
Microstructural stability;
Environmental effects and oxidation resistance;
Materials for energy systems (including fuel cells);
Materials for petrochemical industry;
Materials for fission and fusion nuclear reactors.
