Abstract:Al-B master alloys were ascertained to be efficient grain refiners on pure aluminum. Without introducing any stirring during reaction, three experimental Al-3B master alloys were prepared via the halide salt route by varying the salt addition temperature, i.e. 750, 850 and 950 degrees C. All of them showed grain refining potency on pure aluminum and that with the 950 degrees C addition temperature was found to be the most efficient. Resistance to fading was also noted during holding after inoculation with this master alloy. Crown Copyright (C) 2011 Published by Elsevier Ltd. on behalf of Acta Materialia Inc.
