Abstract
Fatigue failure in metals remains a concern across engineering disciplines, substantially influencing the design, reliability and economic viability of essential load-bearing structure components. Despite notable advances in materials science, fatigue-induced failures—particularly in extreme applications such as deep-space exploration—continue to pose challenges owing to their inherent complex and unpredictable nature. This Perspective provides a concise overview of emerging frontiers in improving fatigue resistance, along with key advancements in our understanding of metal fatigue. It also explores current opportunities and challenges, ranging from the development of promising fatigue-resistant materials through spatially heterogeneous composition and microstructure design to innovations in testing methods, characterization techniques, theoretical frameworks and modelling methodologies for metal fatigue.
