Influence of hold time on cyclic stress response and fracture behavior of an Al–Mg–Si alloy

“…The as-received material is fully recrystallized with fairly large recrystallized grains that were flattened and elongated in the direction of mechanical deformation (rolling plane) ( Fig. 2) [21]. The tensile test specimens conformed to specifications outlined in ASTM E8-90a [28] while the low-cycle fatigue test specimens conformed to specifications outlined in ASTM E606-80 [29].…”

“…For an Al-Mg-Si alloy (Aluminum Association designation 6061) there exist few studies that have systematically evaluated its mechanical behavior [21][22][23][24][25] under both static and dynamic loading conditions. However, there exists limited information in the open literature on the influence of dwell time in tension during fully reversed total strain amplitude-controlled fatigue.…”

Effects of microstructure on high strain rate deformation and flow behaviour of Al–Mg–Si alloy (AA 6061) under uniaxial compression and combined compression and shear loading

“…In particular, these structures have been shown to exhibit relatively high specific strengths, good impact energy absorption characteristics and excellent corrosion resistance. [5][6][7][8][9][10][11][12][13][14] In view of the scientific and technological importance of aluminium alloy based sandwich structures in a variety of impact and/or blast energy absorption applications and the lack of sufficient knowledge of their dynamic structural response, a careful examination of the behaviour of their constituent material elements under high rates of loading is needed. Of all the commercially available heat treatable aluminium alloys, Al6061 is the least expensive and perhaps the most versatile.…”
