Equilibrium pseudobinary Al–Mg2Si phase diagram
Abstract Preliminary experiments and phase diagram calculations were conducted to determine the equilibrium phase diagram of the Al–Mg2Si pseudobinary section. It was found that there is a narrowExpand
Enhanced heterogeneous nucleation in AZ91D alloy by intensive melt shearing
Abstract 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 using aExpand
Mechanisms of enhanced heterogeneous nucleation during solidification in binary Al-Mg alloys
Abstract The mechanisms involved in the grain refinement of Al–Mg alloys through varying the Mg content and applying intensive melt shearing were investigated. It was found that the oxide formed inExpand

In this article, we present an epitaxial model for heterogeneous nucleation on potent substrates. It is proposed that heterogeneous nucleation of the solid phase (S) on a potent substrate (N) occursExpand
Grain refining mechanism in the Al/Al–Ti–B system
Abstract Al–Ti–B is the most widely used grain refiner for many Al alloys. However, the precise mechanism of grain refinement is still not clear after 60 years of intensive research. This work aimsExpand
Microstructural development of Al-15wt.%Mg2Si in situ composite with mischmetal addition
In situ Al-Mg2Si composites, as a new class of ultralight materials for aerospace and other advanced engineering applications, are attracting more and more attention of both material scientists andExpand
Processing of advanced Al/SiC particulate metal matrix composites under intensive shearing – A novel Rheo-process
Particulate metal matrix composites (PMMCS) have attracted interest for application in numerous holds. The current processing methods often produce agglomerated particles in the ductile matrix and asExpand
Bi-continuous metal matrix composites
Bi-continuous alumina:aluminium composites were made by infiltrating an alumina preform which had the structure of a reticulated ceramic foam. The low density preforms were prepared from aExpand
A new approach for the Young's modulus-porosity correlation of ceramic materials
A new approach for determining the Young's modulus of porous ceramics is presented. The approach is based on a previous equation derived for two-phase composites on the basis of a microstructuralExpand
Thermodynamic modelling of the Y–Zn and Mg–Zn–Y systems
The Mg‐Zn‐Y alloy system is rich in intermetallic phases and several stable ternary intermetallic compounds including an icosahedral quasicrystal phase (I phase) exist near the Mg‐Zn edge, making theExpand
