Special Issue Information

Dear Colleagues,

This Special Issue calls for papers addressing the properties and behaviors of metallic materials. Metals and alloys often exhibit changes in their properties and behaviors as a result of different processing routes and treatment conditions. These properties include, but are not limited to, mechanical properties (e.g., strength, hardness, ductility, toughness, fatigue, plasticity and creep resistance), physical properties (e.g., electrical and thermal conductivity, magnetic properties) and chemical properties (e.g., corrosion and oxidation resistance, chemical stability, passivation behavior, electrochemical behavior and resistance to hydrogen embrittlement), as well as weldability. Variations in the properties of metallic materials arise from diverse underlying mechanisms and processing methods. Therefore, it is essential to investigate the relationships between processing methods, material behaviors and resulting property changes.

Metallic materials can generally be categorized into ferrous and non-ferrous metals. Ferrous metals typically include carbon steels, alloy steels and special steels, while non-ferrous metals encompass copper, aluminum, magnesium and titanium alloys, among others. We invite researchers to contribute original research articles and review papers that shed light on  the properties and behaviors of ferrous and non-ferrous metals, high-entropy alloys and other emerging or novel metallic materials for this Special Issue.

This Special Issue focuses on fundamental and applied research related to the properties and behaviors of metallic materials. We welcome submissions on research topics relevant to this Special Issue. Topics of interest include, but are not limited to, the following areas:

  • Processing–Structure–Property Relationships
    Studies investigating the effects of processing routes and treatment conditions (e.g., casting, forming, heat treatment, welding, surface modification) on the microstructure, properties and behaviors of metallic materials.
  • Mechanical Properties and Performance
    Research on strength, hardness, ductility, toughness, fatigue, creep, fracture behavior and deformation mechanisms under various loading and service conditions.
  • Physical and Functional Properties
    Electrical conductivity, thermal properties, magnetic behavior, superplasticity and multifunctional performance of metallic materials.
  • Corrosion, Oxidation, and Environmental Degradation
    Mechanisms and mitigation strategies for corrosion, wear, oxidation and degradation in harsh or complex service environments.
  • Advanced and Emerging Metallic Materials
    Ferrous and non-ferrous metals, high-entropy alloys, lightweight alloys, metal matrix composites and other novel or emerging metallic systems.
  • Advanced Manufacturing and Joining Technologies
    Additive manufacturing, welding and repair technologies, solid-state joining and their effects on microstructural evolution and material performance.
  • Microstructural Characterization and Modeling
    Experimental characterization, multiscale analysis, computational modeling and simulation of microstructure evolution and property prediction.
  • Sustainability and Industrial Applications
    Energy-efficient processing, resource conservation, recyclability and life-cycle considerations, as well as case studies linking metallic material properties to practical engineering applications.

This study investigated 1235D aluminum alloys with varying Zr additions to elucidate how Zr content affects the alloy microstructure and corrosion resistance. The results showed that Al3Zr precipitates refined the grains by pinning grain boundaries. The 0.06% Zr alloy exhibited the finest grain structure, the lowest fraction of low-angle grain boundaries, the lowest geometrically necessary dislocation density, and the fewest microstructural defects susceptible to corrosion. Electrochemical and immersion corrosion tests indicated that the corrosion resistance followed the order 0.06% Zr > 0.12% Zr > 0.02% Zr. The 0.06% Zr alloy exhibited the highest polarization resistance and formed a dense, stable passive film that effectively hindered Cl penetration, thereby minimizing matrix dissolution and the formation of loose hydroxide corrosion products. An insufficient Zr content provided limited grain refinement, whereas excessive Zr promoted precipitate agglomeration; both conditions intensified localized corrosion. Considering both microstructural evolution and corrosion behavior, 0.06% was identified as the optimal Zr addition for this alloy system. These findings provide a theoretical basis for optimizing the Zr content and improving the corrosion resistance of 1235D aluminum alloys in industrial production. Full article

In this study, the Nd:YAG laser process was employed with preselected welding parameters and varying initial welding temperatures (including room temperature, 10 °C, and 0 °C) for spot welding of (Zr53Al17Co29)Nb1 bulk metallic glass. Following welding, the microstructure—including the parent material, heat-affected zone (HAZ), and weld fusion zone (WFZ)—as well as the microhardness, thermal properties, and corrosion resistance of the welds, were systematically investigated. Owing to the low glass-forming ability of the alloy, a small amount of Zr6CoAl2 phase was observed within the amorphous matrix at the center of the bulk metallic glass cast plate. After the laser welding, sub-micron or nanoscale Zr(AlxCo1−x)2 phases have formed in the HAZ of all welded samples, which significantly influenced the microhardness, thermal properties, and corrosion resistance in this region. As the initial welding temperature decreased, both the volume fraction and the density of the Zr(AlxCo1−x)2 phase were reduced. Notably, for the weld performed at the lowest initial temperature of 0 °C, small crystalline phases were detected only at approximately 70 μm below the surface of the HAZ. To clarify the effect of IWTs on corrosion resistance, welded samples were immersed in 6 M HCl at 35 °C for 72–120 h. Surface morphologies after corrosion were examined by SEM in the PM, HAZ, and WFZ. No evident pitting was detected after 72 h of immersion. After 120 h, pitting corrosion was observed on the HAZ surfaces of welds subjected to RT and 10 °C IWTs, whereas no obvious pitting was found at an IWT of 0 °C. The pit size and density in the HAZ increased with increasing IWT. In contrast, no pitting was observed in the WFZ under any IWT condition. Full article
