Possibilities of Application of Amorphous Fe₇₇Cr₂B₁₆Si₅ Alloys in Different States of Thermal Relaxation as Magnetic Tensile Force Sensors

Abstract:

Paper discusses the possible of application of iron-based amorphous Fe₇₇Cr₂B₁₆Si₅ alloys for tensile force sensors. In proposed sensor uniform stresses were generated in direction of the ribbon ring core axis. As a result stresses were perpendicular to the magnetizing field direction, what increases sensor sensitivity as well as simplified analyses. The results show high magnetoelastic sensitivity of Fe₇₇Cr₂B₁₆Si₅ amorphous alloy. Moreover, this magnetoelastic sensitivity increases during the annealing process, which is connected with thermal relaxation of amorphous alloy.
