“…These could successively be used in typical applications of pistons, cylinder liners of automobile engines [6]. Comprehensive studies [7][8][9][10][11][12][13][14][15][16][17] on dry sliding behavior of metal-matrix composites depicts that principal tribological parameters affecting their performance can be categorized as mechanical and physical factors or material factor. The intrusion of hard ceramic particles support the load, largely reduce the wear rate, and also extend the mild wear region as compare to aluminium alloys resulting in enhanced working range.…”

In order to produce energy-efficient material for tribological applications, Al-Fe inter-metallic composites have been produced by liquid metallurgy route. Iron content of the composites varies from 1.67 to 11.2 wt.%. These composites have been tested for their wear properties at different parameters. Debris and wear tracks have been studied in detail to see the surface effects during dry sliding and have been correlated to wear properties. Observations show that low loads and sliding velocities are dominated by oxidative debris and largely covered wear track surface with smooth oxide layer is observed. Whereas metallic debris dominates at higher loads and sliding velocities and highly deformed wear track surface with deep grooves and gross delamination were observed. Further, wear rate is seen to increase continuously with load whereas with sliding velocity it attains a minima after initial decrease and then increases continuously. Low solubility of iron supports the formation of FeAl 3 and an increase in hardness from 95 to 179 VHN continuously improves the wear resistance with increase in percentage iron.

“…C AST ALUMINUM MATRIX particle reinforced composites are gaining significant acceptance because of higher specific strength, specific modulus, and good wear resistance as compared to un-reinforced alloys [1][2][3][4][5][6][7][8]. While investigating the opportunity of using fly-ash as a reinforcing material in the aluminum melt, Rohatagi et al [9,10] observed that the low density of fly-ash may be helpful for making a lightweight composite.…”

The present investigation is focused on the utilization of abundantly available industrial waste, i.e., fly-ash in a useful manner by dispersing it into aluminum/aluminum—magnesium matrix to produce composites by a liquid metallurgy route. Composites are produced with different percentage of reinforcing phase. Further, these composites are characterized using XRD, wet chemical analysis, and image analysis. Mechanical and wear properties of the composites are evaluated.

“…C ONVENTIONAL MONOLITHIC MATERIALS have limitations with respect to achievable combinations of strength, stiffness, and density. In order to overcome these shortcomings and to meet the ever-increasing engineering demands of modern technology, metal matrix composites are gaining importance [1][2][3][4][5][6][7][8][9][10][11]. In the initial stages of metal matrix composites development, emphasis was on the preparation of fiber-reinforced composites.…”

Discontinuously reinforced aluminum matrix composites are fast emerging materials that compete with conventional metallic materials. In-situ particulate composites in comparison with conventional cast particulate composites produced by external addition, promote cleaner interfaces, eliminate interface incompatibility of the matrices with the reinforcements, help to achieve greater thermodynamic stability of reinforcement particles in the matrix at elevated temperature, and also increase the possibility of developing coherency between the matrix and particles formed in-situ. The morphology and the distribution of particles strongly influence the physical and mechanical properties of the composites. In the present study, ilmenite was added to molten aluminum, aluminum—magnesium and aluminum—silicon alloys by vortex method. The oxides present in ilmenite are observed to react with aluminum, magnesium and resulting in production of Al2O 3, MgO and metallic Fe and Ti, which dissolved in liquid aluminum. The strength and hardness value showed considerable improvement. The resulting composites also show appreciable ductility. It is shown that aluminum matrix in-situ particulate composites can be successfully produced with the addition of ilmenite through the casting route in the existing foundries with very little modification.
