Special Issue Information

Dear Colleagues,

You are warmly welcomed to submit a manuscript to our Special Issue “Fabricating advanced metallic materials” of Metals.

Advanced metallic materials are increasingly required for applications in automotive, aerospace/aeronautical, electronic, and bio-medical fields due to their high strength, super ductility, improved thermal resistance, and enhanced conductivity, etc. Fabricating advanced metallic materials involves mechanical/thermal/chemical processing, and the coupling of these processes. These fabricating techniques induce complex chemical composite distribution, hierarchical microstructures and interfaces, textures, etc., and the combination of these factors enable excellent properties of advanced metallic materials. Recent development in fabricating advanced metals has produced fruitful progresses, including innovative fabricating techniques, modern characterization methods, advanced multi-scale modelling, established machine learning models, etc. These progresses have in turn accelerated the development of advanced metals.

This Special Issue focused on fabricating advanced metallic materials by using mechanical, thermal, and chemical processes, both individually and in combination.

In this regard, original research papers, short communications, and review articles studying the following subjects are welcome in this Special Issue: metal fabricating; advanced metallic materials; mechanical processes; chemical processes; microstructure characterisation; computational material science; machine learning.

High-entropy alloys (HEAs) have emerged as a novel class of materials with exceptional mechanical and corrosion properties, offering promising applications in various engineering fields. However, optimizing their performance through advanced manufacturing techniques, like laser cladding, remains an area of active research. This study investigated the effects of laser energy density on the mechanical and electrochemical properties of CoCrFeMnNi HEA coatings applied to Q235 substrates. Utilizing X-ray diffraction (XRD), this study confirmed the formation of a single-phase face-centered cubic (FCC) structure in all coatings. The hardness of the coatings peaked at 210 HV with a laser energy density of 50 J/mm2. Friction and wear tests highlighted that a coating applied at 60 J/mm2 exhibited the lowest wear rate, primarily due to adhesive and oxidative wear mechanisms, while the 55 J/mm2 coating showed increased hardness but higher abrasive wear. Electrochemical testing revealed superior corrosion resistance for the 60 J/mm2 coating, with a slow corrosion rate and minimal passivation tendency in contrast to the 55 J/mm2 coating. The comprehensive evaluation indicates that the HEA coating with an energy density of 60 J/mm2 exhibits exceptional wear and corrosion resistance. Full article
