  ABSTRACT: The present paper reports on the preparation of various Al-5Ti master alloys by the reaction of halide salt (K2TiF6) with molten Al in an induction furnace. The master alloys are supposed to be used for the in-situ processing of Al-TiC Metal Matrix Composites. During the preparation of these master alloys the reaction temperature was varied from 800-1000℃ with the intervals of 100℃, while the reaction time was varied at 45, 60 and 75 min. The binary master alloys prepared were characterized using image analyzer and particle size was measured. It was found that the master alloy Al-5Ti prepared at 8000C, and 45 minutes had a minimum particle size of 9.0 micrometer. Also it is observed that the population of particles less than 10 micrometer decreases at higher reaction temperature.
