| Abstract Scope |
Heterostructured materials (HMs) have drawn large attention due to their potentials to show superior properties that are unattainable by their homogenous counterparts. Recent developments of additive manufacturing (AM), particularly directed energy deposition (DED) have facilitated the fabrication of HMs, thanks to DED’s capability of arranging material compositions and microstructure locally. In this work, we investigate how one can leverage DED to program the mechanical properties of heterostructured bi-material steels. Samples with various materials arrangement designs are first fabricated and tested to compare their tensile properties. The parameters for the design with the best tensile performance are then varied to show how their strength and elongation-to-break can be programmed. Further, we analyse the deformation of such bi-material heterostructured steels and provide insight into the mechanism for the variation in their tensile property. This study offers new opportunities in understanding and optimization of the mechanical properties of steels via the HM approach. |
