摘要
The crystal structure,microstructure and the magnetostriction of Fe83Ga17Dyx(x=0,0.2,0.4,0.6) series alloys were studied.The results showed that the influence of the Dy on the crystal structure of the alloy was very small but the effect on the microstructure was significant when different contents of Dy were added into the Fe83Ga17 alloy,respectively.Meanwhile,the magnetostriction of Fe83Ga17Dy0.2 alloy was greatly enhanced,the magnetostriction λ value reached 300×10-6 at 400(kA/m) magnetic field.
