Special Issue Information

Dear Colleagues,

We are pleased to announce a new Special Issue, entitled "Empowering Industry: Advancements in Cemented Carbides". This Special Issue aims to showcase the latest research, innovations, and industrial applications in the field of cemented carbides. We invite researchers and practitioners in materials science to contribute to this exciting collection.

Cemented carbides, also known as hard metals, are composite materials that combine a metal matrix with hard carbide particles, such as tungsten carbide (WC). These materials possess exceptional hardness, wear resistance and strength, making them crucial in various industries such as manufacturing, mining, cutting tools, automotive, and aerospace.

This Special Issue provides a platform for sharing advancements and breakthroughs in cemented carbides. We encourage submissions that cover fundamental research, experimental investigations, theoretical modelling, and computational simulations. Topics of interest include novel cemented carbide compositions, microstructure design, mechanical and thermal properties optimization, as well as advances in fabrication techniques and characterization methods.

We particularly welcome submissions focusing on applications of cemented carbides in emerging fields, such as the energy, electronics, and biomedical sectors. Additionally, contributions on surface modification, coatings, and modelling of cemented carbide behaviour under different operating conditions are highly encouraged.

Manuscripts should adhere to the journal's guidelines and will undergo a rigorous peer-review process to ensure scientific excellence and relevance to the Special Issue's theme. Original research articles, reviews, and perspectives are all welcome.

Join us in this endeavour to advance the understanding and applications of cemented carbides. Your valuable contributions will empower industries and shape the future of this vital material. We look forward to receiving your submissions.

WC-Ni hardmetals, especially with the addition of Cr, are the first choice for wear parts in a corrosive environment. Despite Ni being studied as a metallic binder matrix in hardmetals for as long as Co, the mechanical properties achieved have consistently fallen behind those of their cobalt-containing counterparts. Due to the rapidly increasing demand for Co, its substitution is of increasing importance. In this study, various alloying elements that do not form strong carbides were systematically investigated as part of a binary Ni-based binder system for hardmetals. Solid and liquid phase sintering were compared by using field assisted sintering and a conventional SinterHIP furnace. The obtained hardmetals were analysed in terms of their microstructure, phases, sintering behaviour, and mechanical properties. The metals manganese, iron, and copper, as well as the metalloids silicon and germanium, were evaluated as additional binder constituents. Hardmetals with a binary Ni-based binder alloy were successfully prepared. The combination with Mn or Si showed the potential to significantly lower the necessary sintering temperature. In particular, Mn proved to be the most effective grain growth inhibitor among the investigated alloying elements. Full article
