چکیده انگلیسی
A simple and effective approach of employing an abrupt increase in growth velocity is presented to obtain entirely coupled eutectics in directional solidification of off-eutectic alloys. Using the proposed approach, the velocity required for the growth of entirely coupled eutectics in off-eutectic alloys can be increased remarkably. In directionally solidified Al–40 wt% Cu hypereutectic alloys with a thermal gradient of 250 K/cm, primary Al2Cu dendrites appeared at constant growth velocities ranging from 5 to 100 μm/s and entirely coupled eutectics formed at 1 μm/s. Employing the abrupt increase in growth velocity, the growth velocity of purely coupled eutectics could attain 100 μm/s.
