Dynamic behavior of extruded AZ61 Mg alloy during hot compression

On the recrystallization behavior of homogenized AZ81 magnesium alloy: The effect of mechanical twins and γ precipitates

“…In addition, it was suggested that the continuous dynamic recrystallization (CDRX) might contribute to the formation of new recrystallized grains. The obtained results for AZ41, AZ51 and AZ61 alloys are also consistent with these achievements indicating the contribution of DDRX and CDRX to grain refinement [15,16]. However, the DRX grain sizes of AZ41, AZ51 and AZ61 alloys were always smaller than those of AZ31 alloy under the same deformation conditions [16,17].…”

Influence of constraint condition on rolling behavior of magnesium alloy at low temperatures

“…Therefore, magnesium alloys do not readily undergo large plastic deformations during the formation of thin strips through cold rolling at low temperatures unless the alloys are subjected to successive annealing treatments between the rolling steps. Instead, rolling is generally performed at temperatures higher than 250°C so that the ductility of the alloys can be improved via the activation of non-basal slip systems [6][7][8]. Hot or warm rolling, however, consumes large amounts of energy and involves long processing times.…”

Lap shear strength and fatigue life of friction stir spot welded AZ31 magnesium and 5754 aluminum alloys

“…To achieve such goals and meet legislative regulations, the manufacturers in the automotive and aerospace sectors have to reduce the vehicle weight via applying advanced lightweight materials [4,5,[9][10][11][12][13][14][15]. Recently, the development and application of the ultralightweight magnesium alloys have been significantly increasing in the transportation sectors due to their low density, high strengthto-weight ratio, and superior damping capacity [1,[9][10][11][12][13]16,17]. On the other hand, aluminum alloys have already been widely used by automotive and aerospace manufacturers due to their excellent combination of lightweighting capacity and strength [8,18].…”
