    Solid-state additive manufacturing (SSAM) has emerged as a transformative class of processes for producing and repairing structural components without melting the feedstock material. By avoiding the melt pool entirely, these processes offer distinct advantages including refined microstructures, reduced residual stress, and compatibility with dissimilar material combinations that are difficult or impossible to achieve through fusion-based methods.
    This special issue focuses on two principal branches of SSAM: friction-based processes — including Additive Friction Stir Deposition (AFSD) and Friction Surfacing — and cold spray deposition. Together, these technologies are advancing applications in aerospace, defense, automotive, and energy sectors, with particular relevance to component repair, coating, and near-net-shape fabrication. Contributions are welcome across the full spectrum of research and development, from fundamental process science and materials characterization to modeling, simulation, and application-driven case studies. Both original research articles and focused review papers are encouraged.

    Topic Areas

    THE SCOPE OF THIS ISSUE INCLUDES BUT IS NOT LIMITED TO:

    • Process parameter development and optimization for AFSD, Friction Surfacing, and cold spray
    • Microstructure evolution and texture development in solid-state deposited materials
    • Mechanical properties: tensile, fatigue, fracture, and hardness of SSAM materials
    • Residual stress characterization and thermomechanical modeling
    • Dissimilar material deposition and multi-material builds
    • Repair and restoration of structural components using SSAM processes
    • Feedstock effects: powder and rod morphology, composition, and their influence on deposit quality
    • In-situ monitoring, process control, and non-destructive evaluation
    • Computational modeling and simulation of material flow and thermal fields
    • Emerging applications in aerospace, defense, automotive, and energy systems
