Amalgamation of al-si alloys and study of their mechanical properties

In the last few years there been a swift increase in the utilization of aluminum-silicon alloys, particularly in the automobile and manufacturing industries, this is because due to their high strength to weight ratio, high wear resistance, low density and low coefficient of thermal expansion. The progressions in the field of application make the study of their wear and tensile behavior an utmost importance. In this present investigation, Aluminum Based Alloys containing 6%, 10%,13%, 16%, 20% and 23% weight of Silicon were synthesized using sand casting method. The tensile, hardness and impact tests are done on different samples of same composition where the results increased with increase in silicon percentage. Yield strength and ultimate tensile strength has increased with increase in silicon percentage. Wear behavior was studied by using computerized pin-on-disc wear testing machine. Resistance to wear has increased with increase in silicon amount and the worn surfaces were analyzed using optical microscope.
