Abstract Scope |
The Al-Ce alloy system offers new opportunities to design alloys specifically for Selective Laser Melting Additive Manufacturing. The inherent rapid solidification of the process induces nanoscale structures that are extremely resistant to thermal coarsening, achieving high strength that is resistant to degradation. Here we will highlight recent work within the Critical Materials Institute exploring additional alloying additions like Mg, Ni, and Fe to Al-Ce through directed energy deposition combinatorial synthesis and rapid property assessment. Results are correlated to thermodynamic predictions of solidification pathway and phase distribution. It is found that additional alloying elements can induce complex changes in phase distribution and strength, both of which are also a function of solidification rate. Promising Al-Ce ternary, quaternary, and quinary alloy candidates for particular applications will also be discussed. |
