Abstract Scope |
Aluminum alloys that exhibit high strength and creep resistance at high temperatures can
be our next-generation fan blades of jet engines and pistons of combustion engines. However,
additive manufacturing (AM) or even welding of these alloys is traditionally challenging due to the presence of hot cracking. We demonstrate a physics-constrained, inverse design framework with data
generated from integrated computational materials engineering (ICME) techniques to explore the
compositional space of Al-Zr-Er-Y-Yb-Ni, and identify an optimal alloy composition achieving
maximum predicted strength at a temperature of 250ºC. Using only 40 sampling data with our
most efficient machine learning algorithm (neural network), we predict a microstructure with
3.5X higher stability of nanoscale hardening phases than a state-of-the-art printable Al-alloy. The
tensile tests at different aging hours validated the predictions. The samples have non-textured equiaxed grains along the built direction and exhibit 400 MPa strength comparable to wrought Al7075. |
