Abstract: The Mechanical properties of Al-Si-Mg (Al 6061) based hybrid composites containing mica particulates of 200 microns and short e-glass fibres of 2-3 cm length in different compositions are studied with stretching/straining and aging. Vortex type of stir casting was employed in which preheated reinforcements were introduced. The test specimens were machined to ASTM standards and were subjected to solution heat treatment and artificial ageing. Double aging was carried out on the specimens with strain and without strain. The properties like Specific wear rate and Hardness are studied and results are presented. A degree of improvement in both Specific wear rate and Hardness was observe in double aged casting with strain over double aged without stress, single aged and as-cast condition. The microstructures of the composites were studied to know the dispersion of the mica and e-glass fibre in matrix. It has been observed that addition of reinforcements significantly improves Wear rate along with Hardness properties as compared with that of unreinforced matrix.
