Special Issue Information
Dear Colleagues,
Very few metals can be found in metallic form in nature; the vast majority have to be processed from their ores at a great cost in terms of energy and money. It is therefore energetically favorable for them to reverse to their initial state. This process is commonly known as corrosion or anti-metallurgy, and great efforts are made worldwide to limit this process.
According to the latest NACE estimation (2013), the global cost for corrosion is equivalent to approximately 3.4% of the global GDP (2.5 trillion US$) not considering environmental consequences or safety issues. A reduction between 15% and 35% could be realized if prevention techniques and proper precaution are used, which means savings between US$375 and $875 billion. Corrosion involves different sectors such as industry, military, civilian, services, etc., in particular energy production, transport, chemical and petrochemical industries, the mechanical industry, and drink and beverage. Among these sectors, most of the constituents are made out of steel, which is the most produced metal in the world (1808 million tons in 2018) or light alloys, mainly aluminium (60.1 million tons consumption in 2018).
A proper alloy design in terms of composition, heat treatments, microstructural features, etc. is mandatory in order to obtain the best combination of mechanical properties and corrosion resistance during operation, reducing maintenance costs and the overall impact on the global economy. In fact, microstructural features can affect both the corrosion of the material itself and also the eventual production of protective layers on their surfaces.
The purpose of this Special Issue is to correlate the key role of the microstructure of steels and light alloys to their corrosion properties.
I invite you to submit both original contributions and review works on this topic, with papers that deal both with the characterization and with corrosion resistance evaluation of different alloys.

Abstract: Stainless steels are used as canister materials for interim storage of spent fuels. As a result, local corrosion behavior of 304L stainless steel has become a concern issue when exposed to marine environments in coastal sites. The experiment was conducted after deposition of simulated sea salt particles on the 304L stainless-steel specimen. It was first covered with a crevice former, and then kept at 45 °C with a relative humidity of 45%, 55%, and 70%, for 400 h and 10000 h. The surface morphologies and electron back scatter diffraction (EBSD) analysis of the corroded region for the 304L stainless-steel specimen are presented in this study. The purpose of this work was to investigate the crevice corrosion behavior of 304L stainless steel under different chloride concentrations, relative humidity and test time conditions. From the experimental results, a threshold chloride concentration for stress corrosion cracking (SCC) initiation of 304L stainless steel was proposed.

Abstract: Additive manufacturing is a crucial and promising process of manufacturing due to its increasing demand in all industrial sectors, with special relevance in those related to metallic components since it permits to lighten the structure producing them in complex geometries with a minimum waste of material. There are different techniques involved in additive manufacturing that must be carefully selected according to the chemical composition of material and final requirements. There is a lot of research devoted to the techniques per se and the mechanical properties of final components but not much attention has been payed yet to the corrosion behavior in different service conditions. The aim of this paper is to deeply analyze the different interactions between chemical composition of different metallic alloys, additive manufacturing processes and corrosion behaviour, pointing out on the effect of the main microstructural features and defects associated to these specific processes, such as grain size, segregation, porosity, among others. Moreover, the corrosion resistance of most used systems obtained by additive manufacturing (AM) as aluminum alloys, titanium alloys, duplex stainless steels are analyzed to provide knowledge that can be a platform to create new ideas for materials manufacturing. Several conclusions and future guidelines for establishing good practices related to corrosion tests are proposed.
