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. Rolling results in the fracture of TiAl3 particles. The amount of deformation required for achieving good grain refinement decreases with increase in rolling temperature. Grain refining efficiency of the master alloy also increases with increase in annealing temperature. The improved grain refining efficiency of the master alloy on annealing is attributed to the increased fraction of TiAl3 and the possible formation of (Ti,Al)B2.
