The effect of rolling texture on the magnetoelastic properties of constant modulus alloys

The effect of rolling texture on both the elastic modulus and the temperature coefficient of the elastic modulus (TCE) in an age-hardenable Fe-Ni-Cr alloy was investigated. Experiments were conducted on cold-rolled and magnetized strips. Tuning forks which were machined from cold-rolled strip to have differently oriented rolling textures were also studied. Fifty percent cold-work was sufficient to produce a strong orientation effect, and, in addition, resulted in an uneven rolling texture over the cross section of the specimen. With an increasing degree of cold-work the elastic modulus and the texture sharpness increased, whereas the dependence of TCEon the texture orientation decreased. Young´s Modulus still increased significantly when a magnetic field was applied to 90% cold-worked specimens. To suppress the ΔE-effect, degrees of cold-work greater than 90% are required.
