Abstract Scope |
There is significant interest in alloys with heterogeneous microstructures, particularly for strength-ductility synergy. The timing of research on heterogeneous and gradient alloys coincides very well with tremendous volume of research on laser powder bed additive manufacturing (LPBAM). While the component design opportunities with LPBAM have been discussed very widely, the potential of control of site-specific microstructure in components has not received that much attention. In this overview presentation, the opportunity to tailor the microstructure will be highlighted. Our work on novel Al alloys designed for printability-performance synergy during LPBAM provided a nice window for obtaining heterogeneous microstructure. The fundamentals behind this approach will be presented. These finding can be generalized to other alloys, and to properties beyond the strength-ductility paradigm. A few general guidelines will be discussed. |
