“…This suggests that the material fracture has been initiated at the places of decohesion of the particles and the matrix. In case of higher content of Al2O3 the initial places of fracture are the particle agglomerates where there is possibility of direct contact of Al2O3 particles [12]. …”

“…AMCs are generally produced either by (1) solid state processing techniques like powder metallurgy, diffusion bonding, physical vapor deposition or (2) liquid state processing methods such as stir casting, infiltration, spray deposition and reactive processing [1,2]. Several researchers have attempted to study mechanical and tribological properties of the aluminium matrix composites [10][11][12][13][14][15][16][17][18][19][20]. Among many other parameters, size of abrasives and %weight of Al 2 O 3 are reported to be the most effective parameters influencing wear, hardness and other mechanical engineering properties of AMCs [15][16][17].…”

Knowledge of hardness is very useful in understanding the ductility behavior of composites and in turn, is paramount in predicting the resistance to crack initiation/propagation.…”

The hardness model was developed for aluminium metal matrix composites having Al7075 matrix reinforced with particles of Al 2 O 3 and fabricated by stir-casting. Four factors, five levels, central composite, rotatable design matrix was used to optimize the number of experiments. Adequacy of the model was tested by employing analysis of variance (ANOVA). The experimental results showed that size of reinforcement was the major parameter influencing the hardness of the composites among the other control factors, followed by weight fraction of reinforcement. However, the holding temperature and time had lower effects. The model suggests that one must take into account the interaction of parameters for predicting hardness of composites so that the optimal combination of the testing parameters could be determined and predicted.

“…In earlier studies, most of the researchers have focused their work with matrices of pure aluminum and its alloys such as 2124, [24] 2009, [25,26] 2024, [27][28][29] 7015, [30] A356, [31][32][33][34][35] 7005, [36] and 6061. [32,37] It is generally accepted that Al 2 O 3 is an ideal reinforcing material for aluminum and its alloys, because it is cheaply and easily available and physically and chemically compatible with aluminum matrix.…”

Metal matrix composites (MMCs) based on AA2218 alloy have been successfully developed by stirring powder mix of TiO 2 particles along with Al 2 O 3 particles prepared by milling into the alloy melt. The chemical reaction of TiO 2 particles with molten Al alloy results in alumina and simultaneously releases into the alloy elemental titanium, which forms intermetallic phase Al 3 Ti in the last freezing liquid at the dendrite cell boundary. Application of squeeze pressure during casting of melt-particle slurry in the pressure range from 100 to 220 MPa results in decreasing the cell size and porosity. Following T61 heat treatment recommended for AA2218 alloy, the composites have been solutionized; their aging response at 170°C shows significant increase due to squeeze pressure, but the peak hardness at 10 hours is relatively insensitive to variation in squeeze pressure. The 0.2 pct offset proof stress and the UTS of squeeze-cast composites after solutionizing and those aged following solutionizing increases with increasing squeeze pressure. The influence of aging as evident from the comparison of their properties starts increasing significantly in composites squeeze cast at 140 MPa but becomes steady after 180 MPa. The ductility of the composites also improves across the pressure range between 140 and 180 MPa, and there is increased improvement in ductility after aging at higher squeeze pressures. The scanning electron microscopy (SEM) micrographs show that squeeze-cast composites show more dimpled regions than those observed in gravity-cast composites.
