polycrystal

Tb-Dy-Fe twin crystal or polycrystal magnetostrictive materials are normally employed as driving unit in magnetostrictive actuator, yet the crystal boundary and twin crystal structure in the Tb-Dy-Fe materials hinder the movement of domain walls so that the displacement output under low magnetic field is rather small.

磁致伸缩型微位移致动器通常采用多晶或孪晶结构材料作为驱动单元，由于晶界和孪晶界对畴壁的移动具有阻碍作用，其低场下的位移输出较小，调控精度受到较大影响。
