| Abstract Scope |
Strengthening of Al alloys is commonly achieved through age hardening. However, achieving well dispersed fine precipitates requires a meticulous heat treatment schedule. Here we report nanocrystalline Al-Pd alloys with self-assembled nanoscale laminates. The nano-laminates consist of alternating Al-Pd solid solution and Al4Pd intermetallics. The Al-Pd alloy exhibits a high flow stress with significant work hardening ability, as evidenced by in-situ SEM micropillar compression tests. We will discuss the unique nano-laminated microstructure induced strengthening and deformation mechanisms of the nanocrystalline Al-Pd alloys. This study offers an alternative approach for the design of high-strength and deformable Al alloys. |
