Abstract
This letter reports the effect of heating rate on the grain refinement of a Ti-46Al-2Cr-2Nb (at.%) alloy by cyclic heat treatment. Results show that m icrostructures with two different sizes were developed at two different hea ting rates. A coarse fully lamellar structure can be refined to a fine one with a size of 15 mum if the heating rate, together with the heating temper ature, is appropriately controlled.
