Abstract
In this paper, Ti–46Al–2Cr–2Nb and Ti–46Al–2Cr–2Nb–0·2B alloys were directionally solidified under different cooling rates. Based on the comparison, the effects of minor B doping on the primary dendrite arm and lamellar spacing were investigated. TiB was formed during solidification before the formation of the lamellar structure. The primary dendrite arm spacing was slightly reduced by TiB when the α phase was solidified as the primary phase. However, the lamellar spacing significantly increased in the Ti–46Al–2Cr–2Nb–0·2B alloy because TiB reduced the undercooling temperature required for the formation of the γ phase.
