Abstract
The response of Al-7Si alloy towards grain refinement by Al-Ti-B master all oys (with different Ti-B ratios) at different addition levels has been stud ied in detail. The results indicate that high B-containing master alloys ar e powerful grain refiners when compared to conventional grain refiners like Al-5Ti-1B master alloys. In the present study, indigenously developed mast er alloys have been used for the grain refinement of alloys Al-7Si and LM-2 5. Significant improvements in mechanical properties have been obtained wit h a combination of grain refiner and Sr as modifier. (C) 2000 Elsevier Scie nce S.A. All rights reserved.
