Abstract
Abstract It is of great interest to replace the K 2 TiF 6 salt so as to reduce the volume of fluoride-bearing particulate material to be added to the aluminium melt in the popular “halide salt” process. Ti sponge was used in the present work as the source of Ti in the production of an Al–5Ti–1B grain refiner. Addition of Ti granules into molten aluminium, either premixed with or before KBF 4 salt, has produced Al–5Ti–1B alloys where the boride particles were relatively few and predominantly of the AlB 2 type. The grain refining efficiency of these alloys were far from satisfactory. TiB 2 was the dominant boride phase with sufficient number of blocky aluminide pa...
