Grain Boundary Segregation of Rare-Earth Elements in Magnesium Alloys
TL;DR: In this article, two Mg-RE systems have been studied using high-resolution scanning transmission electron microscopy that permits both imaging and elemental analysis with a spatial resolution of better than 0.1nm.

The effect of Al8Mn5 intermetallic particles on grain size of as-cast Mg–Al–Zn AZ91D alloy
TL;DR: In this article, the effect of Al 8 Mn 5 particles on grain size of an Mg-9Al-1Zn (AZ91D) alloy was assessed and it was concluded that Al 8 NM 5 particles are unlikely to act as effective nucleation sites for the α-Mg during solidification of Mg−Al based alloys.

Effect of austenite grain size and bainite morphology on overall kinetics of bainite transformation in steels
TL;DR: In this article, an attempt is made to rationalise some contradictory observations on the effect of austenite grain size on the overall kinetics of the bainite transformation in steels.

Structural evolution and phase formation in cold-rolled aluminum–nickel multilayers
TL;DR: In this paper, a modified kinetic model for multilayer reactions was proposed to yield information on the evolution of the distribution of layer sizes during deformation from differential scanning calorimetry (DSC) data.
