Special Issue Information

Dear Colleagues,

This Special Issue aims to present a series of featured articles and reviews exploring the latest advancements in the field of metallic materials and composites. Metallic materials and alloys have been traditionally used since the bronze age and have been constantly under development up to this age of semiconductors. They find applications in various industries, including, but not limited to, aerospace, automotive, biomedical, jewelry, tooling, and structural engineering. This Special Issue aims to compile key developments in the advancements of metallic materials and composites, especially their alloy strategy, processing, structure–property correlations, strengthening and failure mechanisms, sustainability and circular economy aspects, recycling, and modeling and simulation of materials and their properties. By combining theoretical insights and experimental observations with practical applications, this Special Issue aims to foster a deeper understanding of the potential of metallic materials and composites, guiding future research and development initiatives.

This Special Issue invites researchers, scholars, and industrialists to report on their recent findings on the development of metallic materials and composites. In addition, start-of-the-art reviews reflecting on specific aspects of the development of materials and composites are also welcome.

This work is a continuation of our previous research. We successfully produce low-carbon gear steel containing trace tellurium (Te) through industrial production line (EAF-LF-VD-CC), and we investigate the effects of a trace Te addition on the precipitation of MnS inclusions in sulfur-containing gear steel billets, the machinability of rods, and the high-temperature vacuum carburizing performance of rods. This study demonstrates that the addition of trace Te in steel can be achieved in industrial production without causing disruptions in the steelmaking process. The Te addition effectively induces spheroidization and refinement of MnS inclusions in industrial cast billets, showing good consistency with laboratory Te alloying experimental results. Furthermore, the Te addition reduces the deformation rate of MnS inclusions during industrial rolling processes. Benefiting from the spheroidization of MnS inclusions, the chip-breaking performance during the machining of Te-containing rods is significantly optimized, along with substantial improvement in machined surface roughness. The industrial rods exhibit excellent grain stability during 960 °C high-temperature vacuum carburizing, with carburizing rates significantly enhanced compared to conventional gear steels. This work comprehensively demonstrates the multifaceted effects of Te treatment on gear steel properties, particularly providing valuable references for developing high-temperature carburizing gear steels.

Metal nanocomposites are rapidly emerging as a powerful platform for biosensing applications, particularly in the analysis of biological fluids. This review paper examines the recent advancements in the development and application of metal nanocomposites as biosensors for detecting various analytes in complex biological matrices such as blood, serum, urine, and saliva. We discuss the unique physicochemical properties of metal nanocomposites, including their high surface area, enhanced conductivity, and tunable optical and electrochemical characteristics, which contribute to their superior sensing capabilities. The review will cover various fabrication techniques, focusing on their impact on the sensitivity, selectivity, and stability of the resulting biosensors. Furthermore, we will analyze the diverse applications of these biosensors in the detection of disease biomarkers, environmental toxins, and therapeutic drugs within biological fluids. Finally, we will address the current challenges and future perspectives of this field, highlighting the potential for improved diagnostic tools and personalized medicine through the continued development of advanced metal nanocomposite-based biosensors.
