Abstract Scope |
Additive manufacturing has broadened the scope for alloy design, specifically for high temperature aluminum alloys, by employing a faster solidification pathway than traditional casting. Current conventional high temperature aluminum alloys rely on the introduction of high cost elements or the use of rapid solidification to form metastable high temperature strengthening phases. These materials are less feasible for applications needing cost efficiency or complex geometries, and aren’t always adaptable to 3D printing due to susceptibility to solidification cracking. Leveraging HRL Laboratories’ functionalization technique to quickly screen compositions, we have produced a new aluminum alloy consisting of Cr and Zr at concentrations optimized for the unique processing conditions in additive manufacturing. This talk will highlight recent data and analysis that showcases this alloy’s high strength and temperature stability above 300C, with comparisons to current aluminum alloy data. |
