Abstract Scope |
Recent advances in aluminum-cerium alloys have produced outstanding high temperature mechanical properties for an aluminum-based alloy, especially in additive manufacturing applications. Under rapid solidification conditions inherent to AM, the alloys exhibit a nanoscale architecture that is extremely resistant to coarsening. Despite these benefits, the suitability for commercial adaption of alloys depends heavily on its economic viability. A significant fraction of the expense in scaling production of Al-Ce alloys arises from the energy requirements to reduce Ce metal and the associated safety requirements for transporting the reactive pure cerium metal. These costs can be sharply mitigated by exploiting direct reduction of ceramic cerium precursors in molten aluminum. This presentation will focus on how the resulting alloys may offer additional mechanical property and economic benefits, especially when deployed in AM approaches. |
