| Abstract Scope |
Site-specific microstructures in metallic materials offer the potential to develop functional components with tailored properties. However, accurately predicting the mechanical properties of such materials is challenging. In this work, microstructure-based finite element simulation results reveal that, for materials containing randomly distributed identical phases, the mechanical properties are predominantly determined by phase proportion. Based on this finding, a method is proposed to predict the mechanical properties of site-specific material by developing a mathematical model that can predict the properties under varying phase proportions and then incorporating them as material data of the partitioned regions in a finite element model to predict its overall mechanical properties. The proposed method is verified by the experimental tensile test results of the site-specific pearlitic-ferritic steel fabricated using HP’s metal binder jet additive manufacturing technology. This method provides an effective way to predict mechanical properties and can facilitate the design of 3D printing site-specific alloy parts. |
