Effect of solution treatment on the strength and fracture toughness of aluminum alloy 7050

The effects of aging treatment and strain rates on damage evolution in AA 6061 aluminum alloy in compression

“…Both strain rates and aging condition affect the energy absorption capacity of aluminum alloy foams [5,6]. The solution heat treatment temperatures of artificially aged AA 7050 aluminum alloy affect the volume fraction of second phase particles and its fracture toughness [7]. The stability and the amount of various precipitates which strengthens an Al-Mg-Si alloys are not only influenced by the aging condition but also by the Si/Mg ratio [6,8].…”

Effects of Sc and Zr microalloying additions on the microstructure and mechanical properties of new Al–Zn–Mg alloys

“…Dev [8] observed that addition of scandium led to very significant grain refinement in the fusion zone especially for scandium levels greater than the eutectic composition (0.55 wt.%). 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 [4,9,10]. The reports about the aluminum alloys with scandium and zirconium additive s are available but mainly concentrated on the precipitation behaviors of Al 3 (Zr, Sc) particles [11,12].…”

Flow behavior modeling of the 7050 aluminum alloy at elevated temperatures considering the compensation of strain

“…The deformation behavior and the microstructural evolution of the 7050 aluminum alloy have been investigated in the past several decades [4][5][6][7][8]. The existed researches showed that the main soften mechanism of the 7050 aluminum alloy was the dynamic recovery at high Z values, and the continuous dynamic recrystallization was the dominant soften mechanism when the alloy was deformed at low Z values [9,10], and the subgrain size of the 7050 aluminum alloy increased with the increasing of Z values [11].…”
