Design and Manufacture of Heterostructured Metallic Materials

The design and manufacture of heterostructured metallic materials for the balanced improvement of strength and ductility by interior microstructure construction have been the research frontiers and focus in mechanical engineering and materials science. Recently, the understanding of multiple hardening mechanisms in heterostructured metallic materials has progressively advanced. Although establishing quantitative relationships between hardening effects and microstructural parameters and further instructing the research and development of manufacturing for a superior combination between strength and ductility will be of significant value to the design theory, the manufacturing processes and property characterization of heterostructured metallic materials are crucial. In this article, the research progress on the theoretical foundations of designing microstructures and manufacturing processes for heterostructured metallic materials was reviewed. First, the heterostructured metallic materials from the perspective of their microstructural regulation method were categorized. Second, the theoretical foundations for the microstructural regulation of heterostructured materials were reviewed. Third, the manufacturing process for heterostructured materials was classified in terms of the up-bottom and bottom-up approaches as well as reviewed. Finally, the challenges and future development of the design and manufacture of heterostructured metallic materials were addressed.
