Abstract Scope |
Additive manufacturing offers a promising but challenging way to create complex parts. However, the time-consuming and costly testing and qualification of printed parts hinder its widespread adoption. In our study, we investigate 3D printed metallic parts by correlating grain size with thermal history. Thermal history significantly influences solidification and cooling rates, impacting microstructure and mechanical properties. Using Electron Back-Scattered Diffraction characterization and Ansys Software, we determine grain size to study the microstructure-thermal history relationship and predict local yield stress. This can be used to generate a global stiffness matrix and apply boundary conditions to generate a component lifetime. The above analysis can be confirmed by micro-tensile testing of mini samples from various locations is used to link grain size with localized mechanical behavior. This correlation provides a more accurate understanding of the mechanical behavior of 3D printed metallic parts, aiding in predicting their lifetime and accelerating their simulation and qualification. |
