A Study of the Magnetoelastic Effect of Metal Textured Ni–5 at % W Tapes

Resumo

In the temperature range of 50–360 K, the effect of the plane mechanical deformations on the magnetic susceptibility χ_ac(T) of metal biaxially textured Ni–5.0 at % W tapes has been investigated. To create the state of plane stress, the temperature cycling of thin tapes cemented to thick substrates of Si, Mo, Ti, and D16T aluminum alloy has been performed. It has been shown that the main features of the magnetic susceptibility behavior can be explained by magnetoorientation transitions and the appearance of internal stresses σ(T) exceeding the yield strength of the tape material.
