On the interaction of precipitates and tensile twins in magnesium alloys
Chuanlai Liu,Chuanlai Liu,Pratheek Shanthraj,Pratheek Shanthraj,Joseph D. Robson,Martin Diehl,Shuai Dong,Jie Dong,Wenjiang Ding,Dierk Raabe +9 more
TL;DR: In this paper, a crystal plasticity-based phase field model for twinning is employed to study the strengthening mechanisms resulting from the interaction between twin growth and precipitates, and the results indicate that the effective critical resolved shear stress (CRSS) for twin growth increases linearly with precipitate volume fraction and aspect ratio.

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.

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.
