AbstractThe characteristic of the surface morphology of primary alpha phase was studied in a deformed near-alpha titanium alloy. Dendritic alpha phase emerged on the surfaces of primary alpha phase when the alloy was air-cooled in alpha + beta phase field after deformation. The dendritic a grain has the same orientation with its original primary alpha grain. The formation of the dendritic alpha phase could be explained by interface instability in epitaxial growth process of the primary alpha phase. The dislocations induced by deformation could facilitate the formation of dendritic alpha phase leading to the dendritic alpha phase and more obvious with the increase of strain. The growth of dendritic alpha phase was finally limited by the nucleation of second alpha phase with cooling.
