Microstructural Design and Control in Advanced Metallic Materials: From Powder Processing to Additive Manufacturing

Dear Colleagues,

Powder-based technologies offer exceptional capabilities for engineering highly customized microstructures, enabling tailored properties in advanced metallic materials. Through powder metallurgy and additive manufacturing (AM), significant breakthroughs have been achieved, such as enhanced strength, toughness, and fatigue resistance in components with extremely intricate geometries. These technologies might even surpass the performances of conventional manufacturing methods. Developments in powder production are essential for unlocking the full potential of powder-based technologies. Today, varied techniques yield powders with fine particle sizes, spherical morphologies, minimal contamination, and precisely engineered compositions and surface characteristics. These attributes are critical for achieving desired microstructural outcomes. The distinctive microstructures formed from powders also present new opportunities for alloy design. The rapid cooling rates inherent to AM processes can dramatically alter the behavior of alloying elements, though the underlying mechanisms remain an active area of research. Computational tools are increasingly pivotal in this context, reducing the need for extensive experimental research and enabling the predictive modeling of material properties. By integrating computational and experimental strategies, alloy design continues to evolve, paving the way for metallic materials with novel and high-performance characteristics suited to the most demanding applications.

This Special Issue, entitled Microstructural Design and Control in Advanced Metallic Materials: From Powder Processing to Additive Manufacturing, invites contributions that explore the microstructure–property relationship in powder-based technologies. We welcome studies on powder processing, powder metallurgy, additive manufacturing, and the application of computational tools for advancing microstructural design and performance.
