resulted in a shift of magnetostrictive properties parallel and perpendicular to the <100> orientation for the Fe80Ga16A14 alloy.This magnetic field annealing method can aid understanding of the relationship between the microscopic magnetic domains and the macroscopic magnetostrictive properties.It can also aid in further tailoring better magnetostrictive properties within magnetostrictive......
PZT系梯度功能压电驱动器的谐响应特性 陈海1,孟中岩2 (1.上海交通大学复合材料研究所,上海200030;2.上海大学材料科学与工程学院,上海201800) 摘要:研究了PZT系梯度功能压电驱动器谐振状态的机电响应特性,通过改变驱动电场和频率,研究其谐振频率和顶端位移的变化特性.结果表明:增加电场,谐振频率减小,谐振点位移增大,并逐渐趋向饱和.在谐振点附近,悬臂梁弯曲位移达到最大值. 关键词:梯度功能材料; 压电驱动器; 谐振频率; 顶端位移; [全文内容正在添加中] ......

-ray dilatometry. The spontaneous magnetostrictive deformations from 104 to 400 K were calculated. The results show that the spontaneous volume magnetostrictive deformation increases firstly.... The magnetostrictive deformations ωS, λa, λc were determined by means of the differences between the experimental values vm, am, cm of the lattice parameters at a given temperature and the corresponding......
