About this Research Topic
The structure and desired properties of corrosion-wear resistant materials in high-temperature environments largely depends on the dual-phase structural design and surface/interface control. This Research Topic focuses on the design, control and characterization of high-temperature resistant materials. It includes the corrosion and oxidation interfaces, formation mechanisms of corrosion/wear resistant surface films at elevated temperature, microstructural design of dual-phase alloy and synergistic corrosion properties tailored to the unique interface structure with specific chemical, physical, or mechanical requirements. The topic also includes state-of-the-art characterization techniques of the materials (e.g. XPS, SEM, EBSD, TEM, etc.) to assess property degradation at elevated temperature.
This topic will address recent innovation in the field of high-boron Fe-based alloys and other related composites (e.g. boron-containing high-speed steel, B-containing M2 steel, Fe-Cr-B alloys and its coatings, boron-containing stainless steels, Mo-Si-B intermetallics and borides). The corrosion wear performances and thermal shock properties of these materials at high temperature will be investigated to uncover the structure-property relationship and underlying mechanisms. We encourage submissions on the research and development of boride morphology, orientation, doping toughening, cracking and their design and control.
These new materials have potential applications in liquid metal corrosion and hot-dip galvanization. This is due to the barrier effect of borides, as well as the delicate interface design and microstructural control. The directionally solidified boride containing alloys and their corrosion/oxidation at elevated temperature will be collected to evaluate the interface/surface phenomena. The interface evolution and damage tolerance of the alloys during oxidation and corrosion processes will also be summarized.
Important issues of oriented alloys for corrosion and oxidation mechanism will be discussed. Specific microstructural design and fabrication methods of high-temperature boride-containing alloys and related corrosion/oxidation/worn interface structure and adhesion properties will be reported. Embrittlement and stress corrosion cracking due to extreme environments should also be reviewed. In addition to detailing the material science aspects, modelling and simulation approaches may also be included for each of these topics.
Themes of interest are:
-Fe-B based alloys and their oxidation and corrosion properties;
-Interaction of corrosion-wear and/or oxidation-corrosion and its characterization;
-Corrosion/oxidation interface and related interfacial orientation analysis
-Thermal shock damage and stability of laminated structural alloys;
- Development of advanced corrosion wear resistant alloys.
