Journal ArticleDOI
Metal matrix composites: production by the stir casting method
TL;DR: In this paper, the relatively low cost stir casting technique is evaluated for use in the production of silicon carbide/aluminium alloy MMCs, and the technical difficulties associated with attaining a uniform distribution of reinforcement, good wettability between substances, and a low porosity material are presented and discussed.
Journal ArticleDOI
Particle distribution in cast metal matrix composites—Part I
TL;DR: In this paper, a finite element analysis, employing a specialised computational fluid dynamics package, is used to simulate the fluid flow, and thus dispersion of reinforcement material in a molten matrix alloy during stirring.
Journal ArticleDOI
The wettability of SiC particles by molten aluminium alloy
TL;DR: A review of available information on factors which contribute to poor wetting between ceramic phases, and liquid metals is presented in this article, focusing on aluminium, a common MMC matrix material.
Journal ArticleDOI
The enhancement of wettability of SiC particles in cast aluminium matrix composites
TL;DR: In this paper, an innovative approach to fabricating cast metal matrix composite (MMCs) is proposed in order to study the enhancement of wettability of SiC particles by the matrix alloy A359, a casting rig was specially designed, and tests carried out using the A359 matrix alloy, siC particles, and magnesium (as a wetting agent) Stirring of these mixtures was performed under several different conditions, and the effect of this stirring action on the wetability enhancement was studied.
Journal ArticleDOI
Simulation of the stir casting process
TL;DR: In this article, a simulation of the non-homogeneous particle distribution for batch compocasting of metal matrix composites (MMCs) is presented, where liquid and semisolid aluminium are replaced by other fluids with similar characteristics.
