Abstract Scope |
The selection of Al alloys for additive manufacturing is severely limited by the cracking tendencies of most conventional wrought compositions. Al alloy production by AM has therefore been limited to a small subset of highly weldable alloys that generally exhibit poor mechanical properties compared to desirable aerospace grade alloys. These poor properties are especially noticeable at elevated temperatures (between 200 and 500 C) where most Al alloys tend to lose a large fraction of their room temperature strength. This presentation will summarize recent research in Al-Ce-X alloys that are designed for both printability and high-temperature strength. The processing, microstructure, and properties of these alloys will be discussed, and implications for future design and selection of Al alloys for AM printability will be presented as well as the outlook for industrial adoption. |
