Micro-damage behaviors of Al–6Mg alloy impacted by projectiles with velocities of 1–3.2km/s

Influence of grain size on the flow properties of an Al-Mg-Sc alloy over seven orders of magnitude of strain rate

“…Although several investigations were reported evaluating the mechanical behaviour at dynamic strain rates in several UFG metals [48][49][50][51][52][53][54][55][56][57][58], there are no reports are at present available on the deformation of SPD-processed AlMg-Sc alloys at high strain rates. Accordingly, this investigation was initiated to assess the mechanical properties and deformation mechanisms in Al-Mg-Sc alloys tested under quasistatic and dynamic conditions.…”

Twinning behavior and lattice rotation in a Mg–Gd–Y–Zr alloy under ballistic impact

“…A C C E P T E D ACCEPTED MANUSCRIPT 16 The bullet impacted microstructure of GW83K magnesium alloy under a velocity of 400 m·s -1 was investigated in comparison with the original microstructure, and the following conclusions are drawn.…”

“…Analysis of phenomena such as dislocation slip, deformation twinning, recrystallization, phase transformation, amorphization, and micro-hardness evolution, is available in the literature for steel [6][7][8][9][10], copper [1,[11][12][13], aluminum alloys [13][14][15][16], and titanium alloys [17][18][19][20][21][22].…”

Hypervelocity impact damage to Ti–6Al–4V meshes reinforced Al–6Mg alloy matrix composites

“…The pressure P at the impact site is calculated as 23.6 GPa based on shock Hugoniot equation of state (EOS). As for Al-6Mg alloy matrix, T 0 = 300 K, 0 = 2, 0 = 2.7 g/cm 3 , 1 = 3.29 g/cm 3 , C v = 921 J/(kg • C) [7,11]. Eqs.…”

“…The hypervelocity impact behaviors of these composites have also been researched [7][8][9][10]. Silvestrov et al [8] have studied the hypervelocity impact behaviors of thin aluminum matrix composites target containing SiO 2 or Al 2 O 3 inclusions as the first bumper in the single-shielding system.…”
