摘要
The magnetic behaviour of highly magnetostrictive amorphous wires is a direct consequence of the residual stresses developed during the sample fabrication. A phenomenological model that assumes a heat transference from a metallic liquid to the water, with cylindrical symmetry, and a solidification process that propagates in the opposite direction to the heat flow has been proposed. The value for the tensile radial stress field has then been calculated. A maximum value for these radial stresses has been found at a distance of about 0.7 R from the axis of the wire.
