Abstract: The development of advanced materials processing such as casting, powder metallurgy (PM), and additive manufacturing (AM) has played an important role in manufacturing new metal materials. Powder metallurgy (PM) is a widely used metal-forming technology to fabricate dense and precise components. Different powder and component forming routes can be adapted to yield a product with tailored properties for specific applications or industries. Notably, powder metallurgy explores a range of materials and techniques that are being widely used for different application areas. The controlled processing of these powders determines the material’s final mechanical and tribological properties.
Various fabrication routes are employed to customize these powders, including gas atomization, water atomization, and mechanical alloying. These processes offer advantages such as grain refinement and the supersaturation of alloying elements, improving mechanical properties. Advanced consolidation processes are also being explored to create layered structures and composites with superior properties. This presentation aims to provide a comprehensive review of the state-of-the-art methodologies in developing metal powders through PM approaches, highlighting the main concepts and recent advancements in fabrication, especially in gas atomization, water atomization, and mechanical alloying. We will discuss their mechanical, tribological, and thermal properties for structural and functional applications, innovations that redefine conventional PM processes, and the role of different consolidation processes in fabricating layered structures and composite materials.
