Abstract
Ti–6Al–4V alloy castings were obtained with different centrifugal holding time in induction skull melting. The effects of centrifugal radius, riser and centrifugal holding time on the solidification microstructure of centrifugal cast Ti–6Al–4V alloy were investigated in detail. Results show that, under a certain centrifugal holding time, the average grain size of Ti–6Al–4V alloy castings decreases with the increasing in centrifugal radius. The microstructure of the Ti–6–Al–4V alloy casting with riser is finer. Meanwhile, the grain size increases greatly as the centrifugal holding time decreasing from 15 to 1·5 min.
