通过测量非平衡Fe1-xPdx合金的矫顽力Hc与饱和磁致伸缩系数λs,随合金成分的变化,发现Hc随x增加而减小,而λs随x增加而增大。认为晶粒尺寸减小引起的平均各向异性的降低可能是Hc减小的原因。退火温度Ta>600K时,由于具有高磁晶各向异性的有序FePd相的分离析出,矫顽力Hc随Ta升The coercive force, Hc and magnetostriction, λs, have been measured for nonequilibrium Fe1-xPdx alloys, with increasing x, Hc decreases but λs, increases. The decrease of Hc may be related to the decrease in the average anisotropy due to the reduction of crystal grain size. After annealing above 600K, Hc increases rapidly because of the precipitation of the ordered FePd phase.
