文摘
- •
Segregationless solidification was realized in undercooled Ni–13%Ti hypoeutectic alloy.
- •
Primary (Ni) dendrites appeared in highly undercooled Ni–14%Ti eutectic alloy.
- •
Irregular eutectics were formed in undercooled Ni–16%Ti hypereutectic alloy.
- •
The coupled zone of (Ni+Ni3Ti) lamellar eutectic has been predicted.
