Grain refinement of cast magnesium alloys, particularly in magnesium–aluminium (Mg–Al)
based alloys, has been an active research topic in the past two decades, because it has …

Grain refinement leads, in general, to a decreased tendency to hot tearing, a more dispersed
and refined porosity distribution, and improved directional feeding characteristics during …

Magnesium is the lightest constructional metal, which makes it an important material for
different applications like automotive, transportation, aviation and aerospace. There are …

The mechanism underlying the grain refinement of cast aluminium by zirconium has been
studied through examination of a range of Al alloys with increasing Zr contents. Pro …

This paper builds on the “Grain Refinement of Mg Alloys” published in 2005 and reviews the
grain refinement research on Mg alloys that has been undertaken since then with an …

A fine and equiaxed solidification process delivers multidimensional benefits to Mg-alloys,
such as improved castability, reduced casting defects, enhanced mechanical properties …

The grain refining effect of four peritectic-forming solutes (Ti, V, Zr and Nb) as well as three
eutectic-forming solutes (Cu, Mg and Si) on pure Al was investigated. Significant grain …

Intensive melt shearing was applied to the commercial AZ91D alloy melt to investigate its
effects on grain refinement. Alloy melts with and without melt shearing were also filtered …

The paper reviews the current knowledge and understanding of the crystallographic features
of phase transformations in solid materials–metals, ceramics and alloys. It covers both of the …

Graphene and its derivatives have been extensively used as reinforcing agents owing to
their high mechanical properties. In the present work, an attempt is made to synthesize …
