摘要：In this study, Al-Si alloy A356 grain refined and modified using Al-5Ti-1B and Al-10Sr respectivelywas cast in pre-heated permanent mold using liquid metallurgy route. They were further heat treated (T6) bysolutionising at 5400C, quenched in water at 700C and aged for 5 hours at 1800C. They were tested for hardness andwear resistance as per relevant ASTM standards. A quantum rise in wear resistance was observed in Grain refined,Modified and heat treated A356 compared to as cast A356, Grain refined and modified A356. The improvement inwear resistance may be attributed to the refined microstructure, grain refinement and modification and improvedhardness due to heat treatment.
