Alloys and Composites Corrosion and Mechanical Properties, 2nd Edition

Topic Information

Dear Colleagues,

With the development and exploration of marine resources, research on underwater robots and submarines is increasing. However, high-performance materials are necessary for the safe service of ocean equipment, constraining the development of marine equipment. For example, for a steel-structure submarine, its working environment runs through all corrosion areas of the ocean (atmospheric, splash, tidal range and full immersion areas) and involves the interactions of multiple strong fields, such as fluid, temperature, stress and electromagnetic fields. The problems of corrosion, fatigue and other failure behaviors in the shell, frame, pipeline and other parts result in the decrease in the strength of the steel structure, leading to faults and accidents.

Therefore, research on corrosion behavior and protection methods for high-performance alloys and composite materials is becoming more and more important. This Topic aims to collate new research results on the compositional design of alloys, material processing technologies, novel composites and coatings to improve the anti-corrosion and mechanical properties of ocean materials. Original research, reviews, mini-reviews and perspective papers are all welcome.

Papers submitted on this Topic concerning corrosion properties, biofilms, coatings, wear, fatigue mechanics, plasticity, alloys, composites, mechanical properties and processing techniques will be considered for publication. Relevant topics may include, but are not limited to, the following:

• Corrosion properties of alloys in the marine environment;
• Marine structural materials;
• Biofilms and coatings;
• High-entropy alloys;
• Development and exploration of marine resources;
• Wear;
• Fatigue;
• Development of hydrogen storage materials;
• Preparation processes, microstructures, mechanical behaviors and corrosion behaviors of alloys;
• Computational design and modeling.

Achieving a balanced combination of mechanical performance and corrosion resistance remains a critical challenge restricting the broader application of Al–Zn–Mg–Cu alloys in aerospace, marine, and transportation industries. In this investigation, the addition of Si significantly enhances the mechanical properties of the alloy. Among them, the alloy containing 0.35Si has the best corrosion resistance, which is closely related to the transformation of precipitates. A non-monotonic relationship between Si content and corrosion resistance was observed. At low Si levels, the simultaneous precipitation of η, T, and GPB-II phases leads to a large electrochemical potential difference among these phases, which promotes micro-galvanic corrosion. With increasing Si content, the microstructure evolves toward the dominance of GPB-II precipitates, thereby reducing the internal potential difference and improving corrosion resistance. However, excessive addition of Si will lower the equilibrium solid phase temperature, resulting in overburning during the solid solution treatment process and a significant decrease in corrosion resistance. In addition, lowering the solution treatment temperature effectively improves corrosion resistance by suppressing the formation of remelted spheres and low-melting-point brittle phases along grain boundaries. These phases can form strong micro-galvanic couples with the matrix, accelerating anodic dissolution. Therefore, by adding an appropriate amount of Si and optimizing the solid solution temperature, a corrosion-resistant high-strength Al-Zn-Mg-Cu-Si alloy can be obtained. This strategy also provides a broader compositional and heat-treatment design window, which could be further expanded through the incorporation of rare-earth (RE) elements. Full article

This study investigates the development of a high-density W-Ni-Fe alloy using liquid-phase sintering and examines its microstructure and mechanical properties. Critical parameters, including sintering time and heating rate, were optimized to achieve enhanced density, microhardness, tensile strength, and γ-ray shielding properties. The results show that optimal sintering conditions (45 min at a heating rate of 30 K/min and a sintering temperature of 1753 K) lead to a uniform dispersion of tungsten particles, with a high-volume fraction of tungsten in the matrix and enhanced bonding within the γ(Ni-Fe) matrix. The alloy achieved a density of 16.99 g/cm³ and exhibited superior mechanical performance, with a tensile strength of 846.66 MPa and an elongation of 10.5%, as well as excellent γ-ray attenuation capabilities. These results demonstrate its suitability for nuclear applications. Full article
