Abstract
An experimental study has been made of the effect of elastic tensile stresses on the magnetostriction curves of polycrystalline nickel, transformer steel, an equiatomic cobalt-platinum alloy, and an Invar iron alloy with 30–40 wt. % nickel. The sign of the magnetostriction changes during the rotation process under the effect of sufficiently high stress. The effect is explained on the basis of the concept of a magnetic “rotation” texture, developed earlier by one of the authors. A change in the magnetostrictive susceptibility for the paraprocess of the Invar alloy is found to be caused by the stress; the signs of the magnetostrictive constants are determined for the hardened cobalt-platinum alloy.
