Special Issue Information

Dear Colleagues,

Worldwide, more than USD 400 million/year is spent on corrosion protection and productivity losses due to corrosion. Corrosion, a process associated with the chemical/electrochemical reaction, often has a deleterious consequence on mechanical properties, ultimately resulting in the degradation of a material. Metallic components, widely employed in various industries, i.e., oil, gas, marine, nuclear, fuel cells, medicine and generate electricity, often suffer from severe corrosion, which might be detrimental to service life and even cause serious accidents. Meanwhile, some extreme corrosive environments are also the main restriction on applications of advanced metallic materials with excellent mechanical properties. Thus, understanding corrosion behavior and its effect on mechanical properties will always be of great practical significance to the development and application of metallic materials. Corrosion behavior leads to the degradation of mechanical properties, and both are affected by the service environment and the physical and chemical properties of the material itself.  

The purpose of this Special Issue is to provide a research forum to report corrosion behavior, as well the related mechanical properties, chemical composition and microstructure for metallic materials to address existing corrosion challenges and assist in the development of super corrosion-resistant materials.  

Topics of interest include, but are not limited to, the studies mentioned above. Other relevant studies, such as hydrogen embrittlement, characterization of the corroded microstructure, corrosion mechanism of advanced materials, method of surface treatment to improve corrosion resistance, evolution mechanism of mechanical properties in corrosion environment and design of novel corrosion-resistant material, will also be considered, which could enhance the knowledge of corrosion protection. Research articles and reviews in this area of study are welcome.

We look forward to receiving your contributions.

Structural rolled steels are the primary products of modern ferrous metallurgy. Consequently, enhancing the mechanical properties of rolled steel using energy-saving processing routes without furnace heating for additional heat treatment is advisable. This study compared the effect on the mechanical properties of structural steel for different processing routes, like conventional hot rolling, normalizing rolling, thermo-mechanically controlled processing (TMCP), and TMCP with accelerating cooling (AC) to 550 °C or 460 °C. The material studied was a 20 mm-thick sheet of S355N grade (EN 10025) made of low-carbon (V+Nb+Al)-micro-alloyed steel. The research methodology included standard mechanical testing and microstructure characterization using optical microscopy, scanning and transmission electronic microscopies, energy dispersive X-ray spectrometry, and X-ray diffraction. It was found that using different processing routes could increase the mechanical properties of the steel sheets from S355N to S550QL1 grade without additional heat treatment costs. TMCP followed by AC to 550 °C ensured the best combination of strength and cold-temperature resistance due to formation of a quasi-polygonal/acicular ferrite structure with minor fractions of dispersed pearlite and martensite/austenite islands. The contribution of different structural factors to the yield tensile strength and ductile–brittle transition temperature of steel was analyzed using theoretical calculations. The calculated results complied well with the experimental data. The effectiveness of the cost-saving processing routes which may bring definite economic benefits is concluded. Full article

For the dry storage of Canada Deuterium Uranium (CANDU) spent nuclear fuels, the integrity of Zircaloy-4 fuel cladding has to be verified. However, the formation of ~10 µm-thick oxide layers in typical CANDU reactor operating conditions takes several years, which makes sample preparation a slow process. To overcome such limitations, in this study, an accelerated formation of an oxide layer on Zircaloy-4 cladding tube was developed with a combination of high-temperature water corrosion (HT-WC) and air oxidation (AO). First, Zircaloy-4 tubes were corroded in oxygenated (2 ppm dissolved oxygen) high-temperature water (360 °C/19.5 MPa) for 500 h. Then, the tubes were air-oxidized at 500 °C for 30 h. Finally, the tubes were corroded again in HT-WC for 500 h to produce ~10 µm-thick oxide layers. The morphology and characteristics of the oxide layer in each step were analyzed using X-ray diffraction, scanning and transmission electron microscopy. The results showed that the oxide layer formed in the accelerated method was comparable to that formed in HT-WC in terms of morphology and oxide phases. Thus, the accelerated oxide formation method can be used to prepare an oxidized Zircaloy-4 cladding tube for CANDU fuel integrity analysis. Full article

The interactions between displacement cascades and three types of structures, dislocations, dislocation loops and grain boundaries, in BCC-Fe are investigated through molecular dynamics simulations. Wigner–Seitz analysis is used to calculate the number of point defects induced in order to illustrate the effects of three special structures on the displacement cascade. The displacement cascades in systems interacting with all three types of structure tend to generate more total defects compared to bulk Fe. The surviving number of point defects in the grain boundary case is the largest of the three types of structures. The changes in the atomic structures of dislocations, dislocation loops and grain boundaries after displacement cascades are analyzed to understand how irradiation damage affects them. These results could reveal irradiation damage at the microscale. Varied defect production numbers and efficiencies are investigated, which could be used as the input parameters for higher scale simulation. Full article
