| Abstract Scope |
To fully exploit Aluminum’s circularity potential, future alloys must be able to handle increased and fluctuating contents of impurity elements. Advanced eutectics can offer a way to positively utilize both primary and secondary elements from End-of-Life (EoL) waste streams. By nature, eutectic alloys are less dependent on cooling rates in casting, expanding the range of suitable production methods.
An AlMgSi-FeNi-Zn alloy was developed that anticipates a blend of EoL scraps from both aviation and automotive industry. The alloy features an ultrafine, complex multi-phase-eutectic structure that utilizes major (Mg, Si) and minor (Fe, Zn) impurity elements to achieve high mechanical properties at level with modern high-performance casting alloys.
A demonstrator wing segment-structure was successfully manufactured from this novel alloy, blending two industrial scale casting processes with welding using wires of identical composition.
This work focuses on further alloy development on higher Si contents as typical in high volume casting applications. |
