TL;DR: In this article, the hot deformation behavior of the new Al-Mg-Si-Cu aluminum alloy was investigated by compression tests in the temperature range 350°C-550°C and strain rate range 0.005−s−1−5 s−1 using Gleeble-1500 system, and the associated structural changes were studied by observations of metallographic and TEM.

TL;DR: In this paper, the mechanisms of dynamic recrystallization depend on the deformation temperature and are associated with extensive cross slip in Mg-8Al magnesium alloy, and they show that a necklace structure is obtained during the whole deformation process.

TL;DR: In this paper, the tensile deformation and fracture behavior of spray-deposition 7075/15SiC{sub p} (15 vol.% SiC particle) aluminum matrix composite sheet were studied by uniaxial tension tests at temperatures ranging from 300 deg. C to 450 deg.

TL;DR: In this article, the grain refinement capability of the commercially used AA7005 aluminum alloy through a hot deformation process with relatively a low strain level was investigated, and the results indicate that the AA-7005 alloy has a great potential for grain refinement, but special attention should be paid to the parameters.

TL;DR: In this paper, high-speed impact tests were conducted in transverse direction with strain rates (SRs) ranging from 1000−s−1−6−1 to investigate the deformation mechanism and adiabatic shearing behavior of extruded Mg-8.0Al-0.1Mn alloy in as-extruded (AE), low temperature solution-treated (ST1) and high temperature solution treated (ST2) states.
