The role of Sn element on the deformation mechanism and precipitation behavior of the Al–Cu–Mg alloy

Grain Refinement via Changing the Shuffling Motion of the Grain Boundary by Traces of Ce and Lu in Gold Alloys

“…The influence of traces of alloying elements on the mechanical properties of materials has been extensively investigated, and it is confirmed that the strengths of alloys are influenced by the change of grain size induced by alloying. 5 For many systems, such as Mg alloys, 6−12 Al alloys, 13,14 Ti alloys, 15 steels, 16 and oxides, 17,18 the effect of alloying elements on the grain refinement and strength after heat treatment has attracted much attention. For Mg alloys, the influence of 30− 8000 at.…”

Quantifying the effects of Sn on θ′-Al2Cu precipitation kinetics in Al–Cu alloys

“…Therefore, optimising Cu content has an important influence on the age-hardening and mechanical properties. In addition, Sn is considered as an important trace element to restrain vacancy annihilation due to its high binding energy with vacancies [4][5][6]. Studies have shown that Sn promotes the formation of the θ phase by reducing the interfacial energy between the precipitate and the matrix or acting as heterogeneous nucleation particles [7].…”

“…Many studies have reported the effect of Sn on the precipitation kinetics. Most of the studies are based on transmission electron microscopy or 3D atom probe tomography combined with the age-hardening curve [4][5][6]. However, there are few quantitative analyses on the effect of Sn on precipitation kinetics.…”
