Abstract
The influence of hot rolling and annealing of Al-5Ti-1B master alloy on its grain refining efficiency has been studied in detail. Both hot rolling and annealing improve the grain refining efficiency of the master alloy. Rolli ng results in the fracture of TiAl3 particles. The amount of deformation re quired for achieving good grain refinement decreases with increase in rolli ng temperature. Grain refining efficiency of the master alloy also increase s with increase in annealing temperature. The improved grain refining effic iency of the master alloy on annealing is attributed to the increased fract ion of TiAl3 and the possible formation of(Ti,Al)B-2. (C) 2001 Elsevier Sci ence B.V.
