| Abstract Scope |
Additive manufacturing (AM) has been widely applied to produce Al alloys. A majority of the AM Al alloys have mechanical strength comparable to bulk (casted) counterparts. In this talk, we will discuss the mechanical behavior of a custom-designed Al alloy fabricated by laser powder bed fusion (LPBF). The LPBF Al alloy contains heterogeneous microstructures, including microscale and nanoscale intermetallic rosettes. The AM Al alloys have ultrahigh mechanical strength (> 700MPa) and abundant plastic deformability. Post-deformation TEM analyses reveal intriguing microstructure evolutions and deformation mechanisms in the LPBF Al alloys. This study shows proper design of heterogeneous microstructures and precipitates may lead to the discovery of ultrastrong, deformable Al alloys. |
