摘要：

Longitudinal and transverse magnetostriction measurements were performed on polycrystalline Fe100-xTix alloys, for a large Ti concentration range, from x = 8.8 to 34.7 at.%. Our results showed that substituting Fe by Ti does not significantly enhance the magnetostriction. For all Ti concentrations in the magnetically saturated state, the longitudinal magnetostriction values vary from -2 x 10(-6) to 6 x 10(-6). On the other hand, Fe100-xTix alloys exhibit a large forced volume magnetostriction, which increases with increasing Ti-concentration. The magnetostriction behavior could be explained considering investigations of the hyteresis loops and the microstructure.
