“…A considerable amount of studies have been carried out in the area of development of processes, the characterization of the structure, and properties of these materials ( Ref 24,[31][32][33][34][35]. Earlier it has been reported that the production method has a strong influence on the mechanical and tribological properties of composites through its effects on the matrix grain size, porosity, the distribution of graphite particles, and the interfacial properties of the Al/graphite couple (Ref [36][37][38][39]. Improvements in tribological properties are, however, accompanied by a decrease in the strength and ductility of these composites ( Ref 40).…”

To extend the possibilities of using aluminum/graphite composites as structural materials, a novel process is developed. The conventional methods often produce agglomerated structures exhibiting lower strength and ductility. To overcome the cohesive force of the agglomerates, a melt conditioned high-pressure die casting (MC-HPDC) process innovatively adapts the well-established, high-shear dispersive mixing action of a twin screw mechanism. The distribution of particles and properties of composites are quantitatively evaluated. The adopted rheo process significantly improved the distribution of the reinforcement in the matrix with a strong interfacial bond between the two. A good combination of improved ultimate tensile strength (UTS) and tensile elongation (e) is obtained compared with composites produced by conventional processes.

“…The moving direction of the solid particles in the molten matrix is determined by the densities differences between the molten metal and reinforcement particles.High density reinforcement particles move far away in the radial direction compared to the molten matrix particles [3]. Some previous work considers a hollow cylinder rotating vertically around the central axis under the effect of gravity [4]. Experimentation is carried to prepare the samples of 12mm diameter.…”

Aluminum-copper titanium di-boride xTiB 2 ] composite (x = 1%, 1.75%, 2.5%) is prepared successfully by centrifugal casting. Samples pin of diameter 8 mm, 10 mm, & 12 mm are prepared with help of special purpose die. An experimental parameter analysis is obtained for various load and speed combinations on pinon wear disc testing machine. A larger volume fraction of particles can be attained near the wear surface via centrifugal casting. The volume fraction of the heavier titanium di-boride is controlled by inertial forces upon centrifugal processing the semisolid composite. Mathematical Regression Analysis is carried out to calculate wear. Greasy material facilitates heat transfer on the counter side material. Comparative study facilitates wear predictions of Al-4Cu-xTiB 2 metal matrix composite for various practical applications.
