Magnesia (MgO) particles inevitably exist in liquid Mg and may be used as potential sites for
heterogeneous nucleation to achieve effective grain refinement. Understanding of the …

Magnesia (MgO) particles inevitably exist in Al-Mg based alloys and can act as potential
nucleation sites during solidification processing. In this paper we investigated the effect of …

Magnesium, the lightest structural metal, has limited industrial application due to its poor
formability at room temperature. However, the mechanism for the effect of alloying elements …

Based on first-principles density functional theory, the adhesion, stability and bonding
properties of the interfaces between (0001) plane of Mg and (1 1 1) plane of oxide (MgO and …

First-principles method based on density functional theory is applied to calculate the Mg
(0001)/TiN (111) interfacial properties, including adhesion work, electronic structure and …

The introduction of oxide inclusions during the smelting process has a clear promising
heterogeneous nucleation potency on Mg-based alloys, but the mechanism has not been …

Abstract In Mg-Ca alloys the grain refining mechanism, in particular regarding the role of
nucleant substrates, remains the object of debates. Although native MgO is being …

Interfacial segregation of selected elements can be exploited to manipulate the potency of
solid substrates for heterogeneous nucleation, thus controlling the solidification process. As …

It has been reported that native MgO particles in Mg alloy melts can act as heterogeneous
nucleation substrates such that grain refinement of Mg alloys is achieved. A recent study …

Magnesium-rare earth (RE) alloys have received substantial attention over the last two
decades for light-weight fuel efficient applications because of their low density of 1.74 gm/cc …
