Modelling dynamic recrystallisation in magnesium alloy AZ31
TL;DR: In this paper, a dynamic recrystallisation (DRX) viscoplastic self-consistent (VPSC) model is created to predict the continuous DRX and twin-assisted DRX behaviour within an AZ31 magnesium (Mg) alloy over temperatures ranging from 25°C to 200°C. At this temperature range, the active deformation mechanisms and physical phenomena participating in the strain accommodation and texture evolution of Mg alloys are: a basal slip, a prismatic slip, c + a pyramidal slip, { 10 1 ‾ 2 } tens

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.

Kinetics of flow and strain-hardening☆
H. Mecking,U.F. Kocks +1 more
TL;DR: In this paper, a phenomenological model is proposed to incorporate the rate of dynamic recovery into the flow kinetics, which has been successful in matching many experimental data quantitatively, and it has been shown that the proportionality between the flow stress and the square root of the dislocation density holds, to a good approximation, over the entire regime; mild deviations arc primarily attributed to differences between the various experimental techniques used.

Plastic anisotropy and the role of non-basal slip in magnesium alloy AZ31B
Sean R. Agnew,Ozgur Duygulu +1 more
TL;DR: In this paper, a combination of experimental and simulation techniques were used to investigate the plastic behavior of wrought magnesium alloy and found that an increased activity of non-basal dislocations provides a self-consistent explanation for the observed changes in the anisotropy with increasing temperature.
