TL;DR: The influence of the grain size on the flow stress of extruded Mg-3Al-1Zn tested in compression is examined in this paper, where samples with grain sizes varying between 3 and 23 μm were prepared by altering the extrusion conditions.

TL;DR: In this article, a series of tensile test results are reported for the common wrought alloy AZ31 and a simple constitutive model is employed to argue that View the MathML source twinning (which gives extension along the c-axis) can increase the uniform elongation in tensile tests.

TL;DR: In this paper, a series of tensile and compression tests results are reported for common wrought alloys: AZ31, ZK60 and ZM20, and these data are combined with EBSD analysis and simple flow stress models to argue the following: (i) contraction double twinning (which enables contraction along the c axis) can decrease the uniform elongation, and (ii) compression double twinening can also account for shear failure at low strains.

TL;DR: The extrusion behavior, texture and tensile ductility of five binary Mg-based alloys have been examined and compared to pure Mg in this article, and the five alloying additions examined were Al, Sn, Ca, La and Gd.

TL;DR: It is reported that high-quality single-crystalline mono- and few-layer BN nanosheets are one of the strongest electrically insulating materials and more intriguingly, few- Layer BN shows mechanical behaviours quite different from those of few- layer graphene under indentation.
