In this article, the mechanical properties of a precipitation hardenable Al-Mg-Si alloy subjected to cryorolling and ageing treatments are reported in a solid solutionised state.Abstract:
The mechanical properties of a precipitation hardenable Al–Mg–Si alloy subjected to cryorolling and ageing treatments are reported in this present work. The severe strain induced during cryorolling of Al–Mg–Si alloys in the solid solutionised state produces ultrafine microstructures with improved mechanical properties such as strength and hardness. The improved strength and hardness of cryorolled alloys are due to the grain size effect and higher dislocation density. The ageing treatment of cryorolled Al–Mg–Si alloys has improved its strength and ductility significantly due to the precipitation hardening and grain coarsening mechanisms, respectively. The reduction in dimple size of cryorolled Al–Mg–Si alloy upon failure confirms the grain refinement and strain hardening mechanism operating in the severely deformed samples.read more

Influence of Ageing on the Intergranular Corrosion of an Al–Mg–Si Alloy
TL;DR: In this article, the influence of ageing on the susceptibility to intergranular corrosion (IGC) of an Al-Mg-Si alloy has been investigated, where the selected AA6063 Al-alloy has been exposed to ageing treatments at a predetermine temperature of 423 K for durations of 1 to 168 h to achieve the wide range of ageing states covering under- to peak-to over-aged.

Effect of ageing treatment process on the microstructure development and mechanical properties of 6082 Al alloy
TL;DR: In this article , different ageing treatment process was conducted to improve the mechanical properties of 6082 Al alloy, and the results showed that holding at 65 ºC for 336 h after pre-ageing promotes the formation of GP zones and stimulates the transformation of GP zone into β" precipitates during subsequent ageing at higher temperature.

High tensile ductility in a nanostructured metal.
TL;DR: A thermomechanical treatment of Cu is described that results in a bimodal grain size distribution, with micrometre-sized grains embedded inside a matrix of nanocrystalline and ultrafine (<300 nm) grains, which impart high strength, as expected from an extrapolation of the Hall–Petch relationship.

Novel ultra-high straining process for bulk materials—development of the accumulative roll-bonding (ARB) process
TL;DR: In this paper, the accumulative roll-bonding (ARB) method was proposed to introduce high plastic strain without any geometrical change if the reduction in thickness is maintained to 50% every rolling pass.

TL;DR: In this paper, a simple model is proposed to explain the development of a homogeneous microstructure in high pressure torsion (HPT) processing of pure nickel samples, showing that the distributions of grain boundary misorientations are similar in the center and at the periphery of the samples.
