摘要
The microstructure,orientation and magnetostrictive properties of a Fe_(81)Ga_(19)poly crystal grown by Bridgman method were investigated.A big central single crystal surrounded by some small crystals was observed.Lane X-ray back-reflection confirmed the<001>orientation of the central crystal and deviation from the<001>direction for the edge crystals.Subgrain boundaries were monitored in the crystal.It was confirmed that orientations of all the subgrains were very close to the<001>direction.Measurement of the magnetostriction in different crystals indicated the strong anisotropy of the magnetostrictive properties.This work opens the possibility of preparing large-sized single crystal of FeGa alloys by using the Bridgman method.
