| Scope |
Ultrafine-grained and heterostructured (UFGH) materials have drawn great attention from the materials research community due to their exceptional mechanical and functional properties. Heterostructures with architectured microstructure, such as coarse-grained colonies embedded in a fine-grained matrix, multi-length scale twins arranged in a tailored configuration, and the incorporation of transformational phases within non-transformational phases, etc., can achieve outstanding combinations of mechanical performance unattainable in homogeneous materials. The design and formation of heterostructures enable a new perspective to enhance further the properties of UFG materials produced by severe plastic deformation and other processing techniques. Importantly, heterostructured materials can be manufactured using industrial-scale facilities, enabling cost-effective and large-scale production.
The continued advancement of UFGH materials relies heavily on sophisticated characterization techniques that illuminate their complex microstructural heterogeneity and their influence on mechanical behavior. Advanced methods such as high-resolution transmission electron microscopy, in situ mechanical testing, atom probe tomography, synchrotron X-ray diffraction, etc. are pivotal for understanding the microstructural evolution, deformation mechanisms, and grain boundary phenomena inherent to these materials. Such techniques bridge the gap between processing, microstructure, and performance, providing critical insights for tailoring properties and optimizing designs.
