Special Issue Information

Dear Colleagues,

In recent decades it has been widely recognized that preventing the failure of engineering structures necessitates the involvement of a large amount of expertise and, depending on the application, a multidisciplinary and multi-scale approach may be required in terms of both size and time. The series of the International Conference of Engineering Against Failure (ICEAF) aims to provide on a biennial basis a forum to present relevant scientific and technological achievements and to discuss them with an audience of international experts.

The scope of the conference is to attract interdisciplinary work dedicated to the design against engineering failure, the implementation of appropriate guidelines against failure, the development and application of concepts and technologies to prevent failure, the use of both novel and established approaches, technologies, and tools for failure analysis, as well as a deep understanding of the underlying failure mechanisms and the identification of the root causes of failure.

The works are expected to cover a number of different technological areas including aeronautics and space, the automotive industry, the marine industry, wind energy, oil refineries and the chemical industry, civil engineering applications, bioengineering and medical applications, and so forth. The ICEAF VII conference is co-chaired by Spiros Pantelakis (Professor Emeritus, University of Patras, Laboratory of Technology and Strength of Materials) and Michael Vormwald (Professor, Head of Materials Mechanics Group, Technical University of Darmstadt) who will jointly share scientific responsibility for the conference.

The conference website: https://iceaf.eu/2023/home
The opening date for submissions is 26 June 2023.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The aim of this paper was to compare duplex (DSS) and super duplex stainless steel processed by laser powder bed fusion (LPBF) based on the process parameters and microstructure–nanomechanical property relationships. Each alloy was investigated with respect to its feedstock powder characteristics. Optimum process parameters including scanning speed, laser power, beam diameter, laser energy density, and layer thickness were defined for each alloy, and near-fully dense parts (>99.9%) were produced. Microstructural analysis was performed via optical (OM), scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). The samples were subjected to stress relief and high-temperature annealing. EBSD revealed the crystallographic orientation and quantified the phases in the as-built and annealed sample conditions. The as-built samples revealed a fully ferritic microstructure with a small amount of grain boundary austenite in the SDSS microstructure. High-temperature solution annealing resulted in the desired duplex microstructure for both alloys. There were no secondary phases present in the microstructure after both heat treatments. Nanoindentation generated nanomechanical (modulus) mapping grids and quantified the nanomechanical (both hardness and modulus) response; plasticity and stress relief were also assessed in all three conditions (as-built, stress-relieved, and annealed) in both DSS and SDSS. Austenite formation in the annealed condition contributed to lower hardness levels (~4.3–4.8 Gpa) and higher plastic deformation compared to the as-built (~5.7–6.3 Gpa) and stress-relieved conditions (~4.8–5.8 Gpa) for both alloys. SDSS featured a ~60% austenite volume fraction in its annealed and quenched microstructure, attributed to its higher nickel and nitrogen contents compared to DSS, which exhibited a ~30% austenite volume fraction.
