Abstract

Longitudinal and transverse magnetostriction measurements were performed on polycrystalline Fe_{100- x}Ti_x 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 Ã—10^-6 to 6 Ã— 10^-6. On the other hand, Fe_100-xTi_x 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 .
