快速凝固的Fe-29.6at%Pd合金箔表现出更强的磁各向异性和更大的磁致伸缩，为6.5×10−4。这种现象是由激活的马氏体孪晶变体的重排引起的。由X射线衍射和磁化强度-温度曲线得到的逆相变温度分别为293- 333 K和400- 440 K。差异的根源尚不清楚。
Rapidly solidified Fe-29.6at% Pd alloy foil shows a stronger magnetic anisotropy and larger magnetostriction, 6.5×10−4. This phenomenon is caused by the rearrangements of activated martensitic twin variants. The inverse phase transformation temperatures obtained from X-ray diffraction and magnetization vs. temperature curve are 293–333K and 400–440K, respectively. The origin of the discrepancy is unclear.
