Fig. 1.. Schematic process of a new operation showing: (a) Ti-46Al-8Nb bar at the center of heating area while Ti-43Al-3Si seed was placed a little distance away from the heating center; (b) lifting up the seed rapidly and the heating power was reduced for a while; (c) rotation after 5 mm of the crystal growth had been accomplished.
