Abstract Scope |
Additive manufacturing(AM) is a disruptive technology, enables to create the complex parts. However, qualifying the parts remain challenging due to lengthy testing process across various industries. This study aims to accelerate the qualification process by establishing the location-based structure-property relationships using the thermal history. Here, we correlate the grain size with thermal history to estimate the local mechanical properties of the part at various locations by using the established Hall-Petch relationships. The above analysis can be validated by micro-tensile testing of micro samples (3.1mm x 1.2mm x 0.25mm) from various locations, allowing us to link grain size with localized mechanical behavior. Local mechanical properties can define overall performance of the part, these location-based properties could be extended globally by creating the global stiffness matrix and by applying boundary conditions, used to predict the lifetime of a component. Hence, this approach could reduce the time for qualifying an additively manufactured part. |
