Abstract
The response of Al–7Si alloy towards grain refinement by Al–Ti–B master alloys (with different Ti–B ratios) at different addition levels has been studied in detail. The results indicate that high B-containing master alloys are powerful grain refiners when compared to conventional grain refiners like Al–5Ti–lB master alloys. In the present study, indigenously developed master alloys have been used for the grain refinement of alloys Al–7Si and LM-25 . Significant improvements in mechanical properties have been obtained with a combination of grain refiner and Sr as modifier.
