- •
The first time applying the in situ X-ray radiographic observation to the Mg–RE alloys.
- •
The real time solidification of Mg–Gd alloys has been captured.
- •
The dendrite growth direction of Mg–Gd alloys gradually rotates was obtained.
- •
The average primary dendrites arm spacing decreases with increasing cooling rates.
