Abstract Scope |
The development of new Aluminum alloys to include cerium has been investigated to improve the coproduction of mining light rare-earth elements. Ce has been shown to greatly impact the strength of Al-alloys and enhance mechanical properties. With the addition of multiple alloying elements, the strengthening mechanisms may be altered. It is therefore key to understand the phase stability across multicomponent systems to avoid the precipitation of phases that may harm the mechanical behavior of the material. Thermochemical modeling using the CALPHAD method (CALculation of PHAse Diagram) to address the Al-Ce-Cu-Fe-La-Mg-Mn-Ni-Si-Zn-Zr system is presented. The model is applied to design new alloys with within specified composition ranges and include relevant phases that are empirically known to provide strengthening properties.
