摘要
主要研究了Tb对Fe-Ga合金的磁致伸缩性能影响。添加Tb后,Fe-Ga合金具有<100>晶向取向的晶粒数目有所增加,使磁致伸缩性能有了明显的提高。研究了Tb在Fe-Ga合金中的存在位置,Tb原子在合金的晶界处富集。
Effect of rare earth element Tb on the magnetostriction of Fe83Ga17 alloy was investigated in the paper.It showes that addition of Tb to Fe83Ga17 alloy improves the magnetostrictive property of the alloy by aligning the crystalline structure along 100 direction.Tb-rich area was found along grain boundaries.
