Powder Metallurgy Processing of Metals and Alloys

Dear Colleagues,

Powder metallurgy (PM) has become one of the most versatile and sustainable manufacturing technologies for producing metallic materials with tailored compositions, complex geometries, and controlled microstructures. Over the past decades, significant advances have been achieved in powder production, consolidation techniques, sintering technologies, and post-processing methods, leading to remarkable improvements in the structural, mechanical, physical, and functional performance of powder metallurgy components. These developments have expanded the application of PM materials in demanding fields such as aerospace, automotive, biomedical engineering, energy systems, electronics, defense, and additive manufacturing. Recent progress in advanced powder processing including mechanical alloying, spark plasma sintering, hot isostatic pressing, metal injection molding, and powder bed fusion technologies has enabled the fabrication of novel alloys, composites, high-entropy materials, functionally graded materials, and porous structures with unprecedented performance. At the same time, the integration of computational design, artificial intelligence, and machine learning has accelerated the optimization of powder metallurgy processes and the development of next-generation materials. In this context, it is timely to highlight recent advances in powder metallurgy, covering the entire processing chain from powder synthesis and consolidation to microstructural characterization, property evaluation, and industrial applications. The aim of this Special Issue on Powder Metallurgy Processing of Metals and Alloys is to present the latest scientific and technological developments in powder metallurgy, encompassing innovative processing routes, advanced characterization techniques, novel materials, and emerging applications.

We invite researchers to submit original research articles, short communications, and comprehensive review papers related, but not limited, to the following topics:

• Powder production, synthesis, and characterization.
• Powder metallurgy processing, consolidation, and shaping technologies.
• Mechanical alloying and advanced powder processing.
• Conventional and advanced sintering techniques.
• Additive manufacturing and powder-based manufacturing technologies.
• Metal injection molding and near-net-shape processing.
• Structural, microstructural, and phase evolution studies.
• Mechanical, tribological, thermal, electrical, magnetic, and corrosion properties.
• High-entropy alloys, intermetallics, metal matrix composites, and functionally graded materials.
• Porous metals and biomaterials manufactured by powder metallurgy.
• Sustainable and energy-efficient powder metallurgy processing.
• Artificial intelligence, machine learning, and computational modeling for powder metallurgy.
• Industrial applications of powder metallurgy in aerospace, automotive, biomedical, energy, and electronic sectors.
