Abstract
Present article reports the microstructure and wear behavior of grain refined and modified Al-7Si-0.3Mg (LM25) alloy. Combined grain refinement and modification is achieved by inoculating LM25 melt with various inoculation levels (0.2, 0.5 and 1.0 wt%) of a novel Al base master alloy containing Ti, C and Sr (synthesized in the authors' laboratory) at 720 ° C. The wear resistance of LM25 alloy improves with the addition of this master alloy up to 0.5 wt%. It is observed that α-Al cell size and morphology of the eutectic silicon of LM25 alloy have significant effect on the wear resistance of the alloy.
