| Abstract Scope |
Additively manufactured alloys with high strength and thermal stability will be our future fan blades of jet engines, pistons of combustion engines, and vacuum pumps. Here we used CALPHAD-based ICME and machine learning techniques and by exploiting rapid solidification, triggered precipitation of metastable and eutectic phases both at nanoscale. We designed various versions of Al-Ni-Y-Er-Zr alloys which achieve unique properties, such as 530 MPa as-built strength, 20% as built ductility, while the strength in some cases exhibits thermal stability even after aging at 400°C for 48 hrs. We show that substituting Er with Y lowers the cost and increases the volume percentage of metastable phases. Moreover, we show that Al3Zr and Al3Ni lead to broad small fracture network which controls the ductility of the sample. Our comprehensive fundamental designs have various insights for future design of additively manufactured Al alloys for various industrial applications. |
