Developing advanced metallic materials with high strength and ductility is an eternal theme,
however, the strength and ductility are generally considered to be conflicted to each other …

A bimodal microstructure composed of large primary α-Al phases (PPs) and small
secondarily solidified grains (SSGs) is fabricated in 6061 aluminum alloy by powder …

A ductile nanostructured Al alloy with desired microstructure is tailored via the precipitation
optimization and texture design. The microstructure consists of two-dimensional nano …

Alloys with grain or subgrain structures refined down to 1μm or below usually have high
strength, but often inadequate tensile ductility. Past efforts in improving their ductility have …

A new strategy through controlling the aggregation states of alloying elements before cold-
rolling is proposed to tune the nano-precipitation in Al alloys processed by combining …

Simultaneously achieving high strength and ductility has been a long-standing goal in
aluminum alloys, while the increase in strength usually leads to ductility loss. In this study, a …

Methods to strengthen aluminum alloys have been employed since the discovery of the age-
hardening phenomenon in 1901. The upper strength limit of bulk Al alloys is~ 0.7 GPa by …

In response to the critical need for lightweight designs and carbon neutrality, we introduce
an innovative additively manufactured ultrafine-grained Al-Mg-Mn-Sc-Zr alloy reinforced with …

A novel hierarchical nanostructure consisting of nanoscale grains (~ 115 nm), subgrains (~
36 nm), needle-shaped S'/S precipitates (Al 2 CuMg, 6–16 nm in length) in grains and …

Grain refinement is the most universal and effective method of strengthening metallic
materials, which is known as the “Hall-Petch” relationship. However, when grain size is …
