Opis:
Idea of the high-resolution eddy current tomography is presented. Proposed system gives possibility of testing cylinder-shaped elements made of both magnetic and non-magnetic materials. To validate the concept, the tomographic measurements are carried out on set of steel cylinders with non-magnetic copper inclusion. Measurements were done during both linear and rotational movement of the element. Achieved results indicate the high sensitivity of system, which creates possibility of its application for non-destructive testing of the elements made of ferromagnetic and non-magnetic materials.

Opis:
The following paper presents the results of the investigation on the influence of the torque on the magnetic characteristics of the Hitperm-type $Fe_{41.5}Co_{41.5}Cu_1Nb_3B_{13}$ alloy, in as-quenched and nanocrystalline state. The methodology of application of the torque to the ring-shaped core is also described. This methodology gives a possibility of achieving uniform shearing stresses in the core. The results indicate that shearing stress sensitivity of Hitperm-type alloys depends on the annealing and nanocrystallization process. This effect should be considered during the development of magnetoelastic torque sensors.

Opis:
This paper presents the implementation of the extended Preisach model for fluxgate sensor characteristics modeling. The developed model enables the optimization of fluxgate sensor parameters for a given core material. Model consists of two parts. The first one describes magnetic characteristics of the core, while the second part calculates output signal according to sensor dimensions and electric circuit parameters. The model is easy to adapt for modeling of other devices with magnetic cores. It can be used instead of costly and time consuming prototype testing.

Opis:
The paper presents a novel method of measurements of tensile stress dependence of the magnetic characteristics of ring-shaped cores made of soft amorphous alloys. In the presented method, the uniform tensile stress was applied perpendicularly to the magnetizing field direction. Magnetoelastic core with closed magnetic circuit was fixed on the non-magnetic backings enabling the conversion of compressive force into tensile stresses as well as it enables the core to be winded by magnetizing and sensing windings. Magnetoelastic characteristics measured under tensile stress, for $Fe_{25}Ni_{55}Si_{10}B_{10}$ alloy annealed in temperature 350°C for 1 h, are presented in this paper. The presented results indicate high tensile stress sensitivity of $Fe_{25}Ni_{55}Si_{10}B_{10}$ alloy. Moreover, together with magnetoelastic characteristics for compressive stresses (presented previously in the literature), the describes results create possibility of further development of models of the magnetoelastic effects in amorphous alloys.

Paper presents the results of investigations of the influence of the tensile stresses on magnetic characteristics of $Fe_{80}B_{11}Si_{9}$ amorphous alloy in as quenched and annealed state. For the tests, a special methodology of application of uniform tensile stresses to the ring shaped sample was developed. Due to special non-magnetic pads, the magnetizing and sensing coils can be wound around the core. Experimental results indicate high stress sensitivity of $Fe_{80}B_{11}Si_{9}$ alloy in both as-quenched and annealed state. Permeability of the core decreases over 64% and 58% for as-quenched and annealed core respectively, especially for lower values of the amplitude of magnetizing field.

This paper presents the experimental results of the magnetic and magnetoelastic investigation on the properties of $Fe_{70}Ni_8Si_{10}B_{12}$ amorphous alloy, subjected to thermo-magnetic treatment. Samples were annealed at temperature 350°C for 1 hour, in parallel magnetic field (4 kA/m), as well as in transverse field (350 kA/m). Sample annealed without magnetic field was also tested. Magnetoelastic tests were performed under uniform compressive stress, applied to the ring-shaped core, perpendicularly to the direction of magnetizing field. The results indicated that the thermo-magnetic heat treatment changes the magnetic characteristics, but does not have a significant influence on the coarse of magnetoelastic characteristics of $Fe_{70}Ni_8Si_{10}B_{12}$ amorphous alloy.

Opis:
Paper presents the possibility of application of the Jiles-Atherton extended model to describe the magnetic characteristics of construction steel C45 under the influence of tensile stresses. Experiment was performed on the frame-shaped samples. Then, the influence of stresses on hysteresis loops was modelled with the Jiles-Atherton extended model. The obtained results of the modelling are consistent with results of the experimental measurements. The results of modelling create new possibilities of explanation of the physical phenomena connected with magnetisation of the magnetic materials under stresses, which is esential for the assessment of the state of the construction steel during its exploitation in industrial conditions.

Opis:
In the paper the results of investigation on tensile stresses dependence of magnetoelastic characteristics of cores made of 13CrMo4-5 constructional steel are presented. In the investigation step-cooling test treated samples were used. The step-cooling test process is a type of heat treatment simulating effects of passing time and environmental conditions (temperature and stress) on the sample. In the paper the method of testing the influence of stresses on the magnetic characteristics is presented. Frame shaped samples ensured a closed magnetic circuit and homogeneous distribution of stress. It was found that step-cooling test does not significantly influence the magnetoelastic characteristics and the structure of the samples. On the other hand, then tensile stresses significantly change the magnetic characteristics of 13CrMo4-5 constructional steel. That confirms the possibility of using measurements based on the magnetoelastic effect in the stress assessment for industrial non destructing testing of steel constructions.

The following paper presents the original results of investigation on the magnetoelastic properties of ferrite materials magnetized in low field region, which could be utilized in development of force and stress sensors. The objects of investigation were two ferrite materials (manganese-zinc Mn-Zn and nickel-zinc Ni-Zn). The magnetoelastic characteristics of the materials were investigated with the special measurement system, allowing measurement of magnetic parameters of the ferrite materials magnetized with low fields under the influence of the compressive stress. The obtained results indicate that there is a strong correlation between the magnetic properties of the material in low magnetizing field region, and applied mechanical stress, which allows development of the magnetoelastic stress or force sensor with ferrite core working in low magnetizing field region.

Opis:
Information about magnetoelastic properties of newly developed amorphous magnetic alloys is very important from practical point of view, especially in the case of high permeability materials such as the Fe₆₁Co₁₉Si₅B₁₅ amorphous alloy. In the case of such materials, effect connected with the influence of external stresses on the magnetic properties of the alloy should be tested. This paper presents experimental results of the magnetoelastic properties investigation of the Fe₆₁Co₁₉Si₅B₁₅ amorphous alloy, annealed without magnetic field as well as in the magnetic field. Such thermo-magnetic treatment generated anisotropy has significant influence on the total free energy of magnetic material. In the magnetoelastic investigation, the compressive stress was applied to the ring shaped core, perpendicularly to the magnetizing field direction. Due to the fact, that cores with closed magnetic circuits were used, demagnetization did not change the balance of total free energy in the material.
