“…These promising effects are related to the formation of a dense and homogeneous distribution of the L1 2 -structured Al 3 (Sc,Zr) coherent precipitates [5][6][7][8][9][10][11]. The complex nanostructure of the Al 3 (Sc,Zr) phase in aluminium has been discussed in several recent articles by studies using conventional and high-resolution transmission electron microscopy or atom-probe tomography [12][13][14][15].…”

Microstructure, thermal, electrical and mechanical properties of the hot-extruded and hotrolled AlMnScZr alloys were studied. The electrical resistometry and microhardness together with differential scanning calorimetry measurements were compared with microstructure development observed by transmission electron microscopy, X-ray diffraction, and electron backscatter diffraction. Fine subgrain or grain structure developed and fine coherent Al3(Sc,Zr) particles precipitated during hot deformation and subsequent cooling. The distinct resistivity changes are mainly caused by precipitation of Mn-containing particles. The pronounced two-stage development of the Al6(Mn,Fe)-phase precipitation was observed. Nevertheless, the precipitation has a negligible effect on microhardness. The presence of the Mn-containing particles with a size of ∼ 50 nm inside subgrains or grains and ∼ 2 µm at subgrain or grain boundaries has a significant antirecrystallization effect. The combination of Mn, Sc and Zr additions to Al suppresses recrystallization during isothermal annealing at 550• C. Hot deformation has no effect on the apparent activation energy values of the Al3Sc-phase precipitation (Q = 109 kJ mol −1 ) and Al6Mn-phase precipitation (Q = 156 kJ mol −1 ).K e y w o r d s: Al3Sc phase, hot extrusion, hot rolling, activation energy, EBSD, DSC

“…The reports about the aluminum alloys with Sc and Zr additives are available but mainly concentrated on the precipitation behaviors of Al 3 (Sc, Zr) particles [15][16]. Desirable service performance from additions of minor Sc and Zr in aluminum alloys is mainly attributed to the presence of coherent, L1 2 -ordered Al 3 (Sc, Zr) particles [17][18].…”

“…Among these alloys, wrought alloys based on the AleMg system [6,7] are used most widely. Despite its high cost, at the moment scandium is considered to be one of the most promising alloying elements in new-generation aluminium alloys [2,8].…”
