Special Issue Information

Dear Colleagues,

The high-temperature oxidation and corrosion of structured materials is a field of research that focuses on understanding the behavior of materials at elevated temperatures in aggressive environments, such as those that encounter high-temperature industrial processes, aerospace applications, and energy generation systems. Structured materials refer to materials that possess complex microstructures, including porous materials, composite materials, and coatings. Understanding the high-temperature oxidation and corrosion behavior of structured materials is crucial for the development of advanced materials with improved performance and durability in high-temperature environments. This research has applications in various industries, including aerospace, energy, chemical processing, and materials processing, where materials are exposed to high temperatures and corrosive environments. The findings from these studies can contribute to the design and development of new materials with enhanced resistance to high-temperature oxidation and corrosion, and can help to improve the efficiency and reliability of high-temperature applications in various industries.

This Special Issue welcomes articles aiming to investigate the fundamental mechanisms and kinetics of high-temperature oxidation and corrosion, as well as the mechanical performance and durability of structured materials under extreme conditions. This includes studying the interactions between materials and reactive gases, such as oxygen, water vapor, and corrosive species, at high temperatures, and how these interactions can lead to material degradation, including oxidation, corrosion, and other chemical reactions.

As the primary choice for aero-engine turbine blades, creep resistance is an important mechanical property for the developing third-generation single crystal Ni-based superalloys. The creep behavior of the superalloy in the [001] orientation was studied at 980 °C under a series of stress levels, accompanied with scanning electron microscope (SEM) and transmission electron microscope (TEM) observation to investigate the microstructure and deformation mechanism. The deformation mechanism of the alloy is found to be dislocation gliding, propagating and forming a dislocation network in the γ/γ′ interface. Dislocation networks could hinder the movement of dislocation and decrease the creep rate to a constant during the steady-creep stage. The formation of dislocation networks was analyzed due to the interaction of <110> {111} dislocations. Then dislocations cut into γ′ phases as individual <110> super-dislocations, anti-phase boundary dislocation pairs, and stacking faults. The <110> super-dislocation in the γ′ phase may cross-slip into the {001} plane from the {111} plane to form Kear–Wilsdorf locks, which could inhibit dislocations from gliding or cross-slipping and then enhance the creep resistance.
