Effects of heat treatment on microstructure of directionally solidified Ti-45Al-8Nb-(W, B, Y) alloy

The effects of heat treatments on typical microstructures of directionally solidified (DS) Ti-45Al-8Nb-(W, B, Y) (molar fraction, %) alloys prepared by the Bridgeman method were studied. Two typical DS microstructures including full lamellae with cellular growth morphology and massive structure with...
