| Abstract Scope |
Printable Al-alloys are in high demand for structural applications in automotive and aerospace industries due to their high strength-to-density ratio. These alloys can be tailored for use at room temperature in housing and brackets, and high-temperature in intake fans and engine pistons. We recently explored and experimentally validated a design pathway for a record high-strength Al-alloy by exploiting metastable ternary phases. At room temperature, these phases impart high strengthening, and transform into nanometer scale, high-temperature stable L12 precipitates to exhibit high-temperature strengthening. CALPHAD-based ICME techniques and Bayesian optimization were used to adapt these designs for high demand industries, i.e. considering elemental costs and sustainability metrics in the design. We identified Al-Ni-Er-Zr-Y as a promising alloy family for both applications. Candidate alloys were experimentally validated by performing characterization via SEM and TEM and tested for hardness and tensile strength. |
