Abstract

Frit-Al6061 alloy composites having 2 wt%, 4 wt%, 6 wt%, 8 wt% and10 wt% of frit particles were fabricated by liquid metallurgy (stir cast) method. The casted ingots were subjected to T6 heat treatment to optimize the properties. The composite specimens were machined as per test standards. The specimens were tested to know the common casting defects using ultra-sonic flaw detector testing system. Some of the mechanical properties have been evaluated and compared with Al6061 alloy. Significant improvement in tensile properties, compressive strength and hardness are noticeable as the wt % of the frit particles increases. The microstructures of the composites were studied to know the dispersion of the frit particles in matrix. It has been observed that addition of frit particles significantly improves ultimate tensile strength along with compressive strength and hardness properties as compared with that of unreinforced matrix.
