What are the characteristics of cemented carbide powder metallurgy?

　　 Cemented carbide powder metallurgy It is a manufacturing process that uses metal powders, or mixtures of metal and nonmetal powders, as raw materials, which are then shaped and sintered to produce metallic, composite, and various other types of components. Powder metallurgy shares similarities with ceramics, as both rely on powder sintering; consequently, many novel powder‑metallurgy techniques can also be applied to ceramic fabrication. Owing to its advantages, powder metallurgy has become a key enabler for addressing emerging challenges and plays an increasingly important role in technological advancement.

　　Powder metallurgy of cemented carbides involves both powders and finished components. The powder‑based processes are, by definition, integral to the metallurgical approach. However, powder‑metallurgy‑derived products often extend far beyond the traditional scope of metallurgy, embracing multidisciplinary methods that integrate metallurgy, mechanical engineering, and mechanics, among others. In particular, modern additive manufacturing of metallic powders—such as 3D printing—fuses techniques from mechanical engineering, CAD, reverse engineering, layered fabrication, numerical control, materials science, and laser processing, transforming powder metallurgy into a cutting‑edge, cross‑disciplinary, holistic methodology.

　　Powder metallurgy of cemented carbides exhibits unique chemical compositions and mechanical and physical properties that cannot be achieved through conventional casting methods. By employing powder metallurgical techniques, it is possible to directly produce porous, semi‑dense, or fully dense components—such as planetary bearings, gears, cams, guide rails, and cutting tools—using a machining‑free manufacturing process.

　　(1) The powder metallurgy method for cemented carbides can effectively reduce compositional segregation and eliminate coarse, non‑uniform as‑cast microstructures. It plays a crucial role in the preparation of high‑performance rare‑earth permanent magnets, rare‑earth hydrogen storage materials, rare‑earth luminescent materials, rare‑earth catalysts, high‑temperature superconductors, and novel metallic alloys—such as Al–Li alloys, heat‑resistant Al alloys, high‑temperature alloys, powder‑metallurgy corrosion‑resistant stainless steels, powder‑metallurgy high‑speed steels, and intermetallic compounds for high‑temperature structural applications.

　　(2) It is possible to prepare a series of high-performance non-equilibrium materials exhibiting superior electrical, magnetic, optical, and mechanical properties, including amorphous, microcrystalline, quasicrystalline, nanocrystalline, and supersaturated solid-solution phases.

　　(3) Powder metallurgy of cemented carbides can readily facilitate the fabrication of various types of composites, fully leveraging the unique properties of each constituent phase, and represents a cost-effective process for producing high-performance metal–ceramic composites.

　　(4) Powder metallurgy of cemented carbides enables the production of novel porous biomaterials, porous separation membranes, high-performance structural ceramic abrasives, functional ceramics, and other materials with unique structures and properties that cannot be achieved by conventional smelting methods.

　　(5) It can be formed almost seamlessly and extensively automated, effectively reducing resource and energy consumption.

　　(6) A new approach for recycling ores, tailings, steelmaking sludge, mill scale, and scrap metals as raw materials.
