  • Ceramic Materials for Advanced Application
    Vol. 2 No. 2 (2024)

    The tremendous demand for ceramic materials with task-specific properties in diverse fields of human life is undeniable. These demanding applications impel the development of low-weight materials with outstanding corrosion and wear resistance and mechanical and thermal stability. Despite the other materials, ceramics have a vast spectrum of attractive properties, including low thermal conductivity, lightness, thermal shock resistance, and chemical inertness. Ceramics is hard but brittle. On the other hand, metal materials are typically malleable and ductile due to metallic bonding and its non-directional nature. They are relatively good conductors of electricity and heat, but their low corrosion resistance limits their application.

    Advanced materials generally have assembled characteristics towards improved strength and toughness, higher operating temperatures, and durability. Careful control of the composition and manufacturing conditions precisely upgrades specific advanced materials, recommending them for aerospace, defense, power generation, and processing industries; for instance, developing alloys for laser hybrid welding results in a fine-grained microstructure that leads to high-strength welds. Also, the demanding application of ceramic refractories as furnace linings in metallurgy, especially in casting operations, implies materials resistant to cavitation erosion. In addition, producing durable refractories starting from natural materials could diminish the amounts of deposed mining tailing noted as waste. Furthermore, the novel characterization techniques and well-established knowledge from metallurgy provide more precise insight into strengthening and toughening mechanisms in ceramics.

    Laser technology uses the phenomenon of stimulated radiation (emission) and amplification of light radiation as an energy source. In indirect laser interaction with Al-alloys, laser impact treatment is often used. In this process, significant coating mixing with the substrate is carried out, forming an alloyed surface layer with new phases and compositions. Bonds of ceramic and metal systems of various compositions can also be formed this way.

    In this regard, the current issue of Metallurgical and Materials Data provides the recent research progress in advanced ceramic materials with new approaches. At present, the biggest challenge in industrial applications is fabricating engineering parts that are mechanically and thermally stable, corrosion-resistant, and durable. Thus, the advanced materials improve productivity, operating costs, performance, and quality.

  • Advanced Biomaterials in Demanding Applications
    Vol. 2 No. 1 (2024)

    The first dental prosthesis, which was a hybrid material from a cow's tooth connected to an Au wire, is attributed to the Etruscan civilization around 2600 years ago. It was used to replace upper incisors by connecting them to adjacent teeth with Au wire.

    The intensive development of biomaterials began in the 60s of the last centuries, with the founding of the American and European Societies for Biomaterials. They accepted the definition of biomaterials, which states that these are materials intended to replace a part or the entire organ in a living organism. The very definition dictates the challenge that knowledge from other scientific fields can be transferred to completely new possibilities of biomaterials, especially in the part of demanding applications. In the 21st century, biomaterials have become a fundamental subject in academic, specialist, and doctoral studies.

    In the current edition of Metallurgical and Materials Data, the goal is to show advanced biomaterials that, with an understanding of functional properties, are used for very demanding applications, if harmony is achieved in their interaction with tissue. This means that the biomaterial is a systematically and pharmacologically inert substance, designed for implantation inside or for inclusion in living systems.

  • Hydrometallurgy: Extraction, Recovery, and Environment
    Vol. 1 No. 2 (2023)

    This issue is dedicated to our dear friend, Professor Fathi Habashi.

    Professor Fathi Habashi was a gifted lecturer and a prolific writer of scientific literature.

    He started his professional career as a chemical engineer in Egypt, then completed his PhD in Austria, and finally moved to Canada, where he became a renowned metallurgist.

    Professor Habashi visited Serbia several times, gave lectures at conferences, and visited faculties and other academic institutions.

    His insightful approach to the development of metallurgy and advice on the selection of technology will remain in the memories of his colleagues.

  • Advanced Functional Materials
    Vol. 1 No. 1 (2023)

    Dear Colleagues,

    Advanced Functional Materials have generated significant research and development interest in recent decades, as they are integral to numerous innovative and disruptive technologies, with the potential to transform manufacturing industries and the economy. We are delighted to announce the release of a new issue of the journal Metallurgy and Materials Data, which highlights the latest developments in the field of advanced functional materials.

    The issue includes an overview of a database for biocompatible titanium-based materials, highlighting their potential medical applications, accompanied by a research paper on the corrosion stability of anodized ultrafine-grained titanium in human body solutions. Also, a study on photocatalysis shows how well Sr0.9La0.1TiO3 and Sr0.25Ca0.25Na0.25Pr0.25TiO3 perovskite-based catalysts remove metoprolol and pindolol under different types of radiation (simulated solar, LED, and UV radiation). There is also a study of how the ratio of balls to powder affects the mechanical and structural properties of CuZrB composite materials made with powder metallurgy. Lastly, the review paper explores the applications of polyaniline-based composites in environmental protection engineering.

    We invite you to join us in exploring the fascinating world of advanced functional materials and to join the ongoing conversation about the future of this field.
