Abstract

Smart metallic materials, recognized for their responsiveness to external stimuli, have garnered significant attention in advanced technological applications. This review focuses on three pivotal smart materials: high-entropy alloys (HEAs), shape-memory alloys (SMAs), and soft magnetic materials, addressing their processing techniques, properties, and applications. HEAs, characterized by their multi-principal elemental compositions, exhibit exceptional mechanical strength, corrosion resistance, and thermal stability, positioning them as promising candidates for extreme environments. SMAs, renowned for their ability to recover original shapes under thermal or mechanical stimuli, find widespread use in actuators, sensors, and biomedical devices. Soft magnetic materials, with low hysteresis loss and high permeability, are critical for energy-efficient systems, such as electric motors and transformers. The review further explores diverse processing methodologies, including conventional melting, Taylor wire fabrication, and advanced additive manufacturing (e.g., 3D printing), which enable precise control over microstructures, material properties, and component design to enhance performance and functionality. Emphasis is placed on the integration of these materials into smart systems, highlighting their synergistic roles in emerging technologies. Challenges, such as material stability, scalability of processing techniques, and the development of multifunctional composites, are critically discussed. Finally, future research directions are outlined to address these limitations and advance the field toward next-generation intelligent material systems. This comprehensive analysis aims to bridge the gap between material design, processing innovation, and practical applications, offering insights for researchers and engineers in optimizing smart material solutions.
