Abstract Scope |
High-strength wrought aluminum alloys are widely used in automobiles and aerospace industries owing to their high-volume precipitates after heat treatment. Investment casting as one of the precision manufacturing methods provides great potential to achieve excellent surface finishes and complex geometry for aluminum alloy components. However, these high-performance aluminum alloys are almost impossible to be investment cast due to their hot cracking susceptibility and severe shrinkage during solidification. Here, in this study, we introduce nanotechnology to improve the processability of high-strength wrought aluminum alloys in investment casting by adding a small volume fraction of nanoparticles into the aluminum alloys. This work showed the unprecedented success of nanotechnology-enabled investment casting of high-strength wrought aluminum alloys for excellent mechanical properties. The ductility and tensile strength were further improved after T6 heat treatment. |
