Characterization of the Magnetostrictive and Elastic Properties of Polycrystalline Co70Fe30 Alloy

The magnetostrictive property of Fe alloys is generally correlated with their elastic property, which is referred as the magnetoelastic effect. However, the correlation is not necessarily clarified in practical polycrystalline Fe alloys with texture. To understand the properties of polycrystalline Co 70 Fe 30 alloys, the properties in alloys with texture must be studied. In this study, the anisotropy of the properties of the alloy sheets was investigated by measuring the magnetostriction and Young’s modulus of the alloy sheets. The results showed that the magnetostriction of the sample with (001) texture component was high, which was fairly consistent with the values of the Young’s modulus of the alloy sheets.
