Abstract Scope |
Some heterogeneous structures have been proved benefitial for simultaneous enhancement of strength and ductility of metallic materials. Heterogeneous structures in metallic materials can be introduced by various methods, including surface plastic deformation, laser shock peening of surface, and chemical/physical deposition. Recently, there has been growing interest in using additive manufacturing (AM) techniques to produce heterogeneous metallic structures. AM of metallic materials involves cyclic rapid thermal loadings that significantly impact the microstructure and consequently the mechanical properties of the materials. During the AM processes, different layers experience different thermal histories, leading to microstructure variation along the build direction. Further, the layer-by-layer deposition during the AM processes makes it possible to precisely manipulate local composition. In this presentation, I will examine the impact of structural heterogeneity on the mechanical properties of AM materials and explore the potential for leveraging AM processing to create hierarchical heterogeneous structures for outstanding mechanical performance. |
