The article presents the stress impedance investigation of CoFeNiMoBSi alloy in variation of the applied magnetic field. In order to carry out the study, a specialized stand was developed that allows for loading the sample with stresses and simultaneous action of the DC (direct current) magnetizing field. The tests were carried out for as-cast and Joule annealed samples. The significant influence of the magnetizing field acting on the sample on the stress-impedance results was demonstrated and the dependence of the maximum impedance change in the stress-impedance effect was determined, depending on the field acting. The obtained results are important due to the potential use of the stress-impedance effect for the construction of stress sensors.
本文介绍了CoFeNiMoBSi合金在施加磁场变化时的应力阻抗研究。为了进行这项研究，开发了一种专门的试验台，该试验台能够对样品施加应力并同时施加直流磁化场。对铸态和焦耳退火样品进行了测试。证明了作用在样品上的磁化场对应力阻抗结果有显著影响，并确定了应力阻抗效应中最大阻抗变化与作用磁场的依赖关系。由于应力阻抗效应在应力传感器构建方面的潜在应用，所获得的结果具有重要意义。
