Texture evolution in equal-channel angular extrusion
TL;DR: In this paper, texture development in metals of fcc, bcc, and hcp crystal structure processed by a severe plastic deformation (SPD) technique called equal-channel angular extrusion (ECAE) or equal channel angular pressing (ECAP) is discussed.

Plastic strain-induced grain refinement in the nanometer scale in a Mg alloy
TL;DR: In this article, the strain-induced grain refinement process in AZ91D alloy includes three steps, at the initial stage twinning dominates the plastic deformation and divides the coarse grains into finer twin platelets, with increasing strain, double twins and stacking faults form and a number of dislocation slip systems are activated.

Achieving ultrafine grain size in Mg–Al–Zn alloy by friction stir processing
TL;DR: In this article, the mean hardness of the UFG region reaches ∼120Hv, which is more than twice as high as that of the AZ31 matrix, and the grain refinement kinetics are analyzed and the results are self-consistent.

Magnesium: Properties — applications — potential
B.L Mordike,T Ebert +1 more
TL;DR: Magnesium is the lightest of all metals used as the basis for constructional alloys and it is this property which entices automobile manufacturers to replace denser materials, not only steels, cast irons and copper base alloys but even aluminium alloys by magnesium based alloys as discussed by the authors.

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.
