Alignment behavior of primary Al3Fe phase in Al–Fe alloy under a high magnetic field

The influence of a high magnetic field on the alignment behavior of primary Al3Fe phase in Al–Fe alloy was investigated. It was found that the primary Al3Fe phase with plate-like morphology was gathered at the bottom of the sample without the high magnetic field. However, they aligned perpendicularly to the magnetic field direction and their homogeneous distribution throughout the sample was achieved when the high magnetic field was imposed. The results of X-ray diffraction (XRD) showed that the paramagnetic Al3Fe phase was magnetized to align to a preferred direction <543> due to crystal magnetic anisotropy in the high magnetic field up to 12 T.
