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:
Paper presents the new methodology of application of uniform torque to the ring-shaped magnetoelastic sensing elements. The results of investigation on the influence of a torsion on the magnetic properties of different amorphous Fe-based ring cores are also presented. The results of tests on Fe Si B amorphous alloy in as-cast and annealed state as well as Fe Nb Cu Si B nanocrystalline alloy indicate, that torque sensitivity is connected with both alloy composition and state on the alloy. Moreover the most sensitive is F amorphous alloy in annealed state. As a result this alloy is the most suitable as a core of magnetoelastic torque sensors.

Opis:
The paper presents the results of investigation of the temperature influence on the inductance and power losses in ferrite cores. Such effect can significantly influence the utility parameters of electronic devices, particularly in precision equipment. For example slight parameter change in this type of components in measuring devices can cause significant changes in output parameters. It is also equally important for mobile devices where increase of losses can limit the duration of service. Special measurement system composed of hysteresis graph, cryostat and PC was utilized to perform the experiment. The cores used during the investigation had closed magnetic circuit. In order to perform measurements of magnetic properties of the material, two sets of windings (magnetizing and sensing) were made on each core. The cores were placed in a cryostat, which was used to set the temperature value within the range from -20 to +50°C. The magnetic properties were measured by the hysteresis graph, to assess the influence of the temperature on the functional parameters.

Opis:
The following paper presents original results of study on the magnetoelastic properties of Ni-Zn (nickel-zinc) ferrite material under low magnetizing fields, corresponding to the so-called Rayleigh region. The investigated $Ni_{0.36}Zn_{0.64}Fe_2O_4$ material was formed into frame-shape sample allowing to obtain uniform stress distribution. Special digitally controlled measurement system was utilized to perform investigation. Obtained results are presented in the paper. On the basis of them mathematical description of magnetoelastic effect in investigated material was developed as an extend of the Rayleigh model of magnetic hysteresis. Comparison of the experimental and modeling results indicates that the developed model is correct.

Opis:
This paper presents the results of investigation on the tensile stresses dependence of magnetic characteristics of the L17HMF steel casting. To ensure uniform stress distribution in the sample for this investigation and the closed magnetic circuit, the frame-shaped samples were used. This is very important because it provides results independent of the shape and dimensions of the sample. On the columns of the sample both sensing and magnetizing windings were made. It is highly recommended to wound magnetizing and sensing windings on both columns. Due to the specialized force reversing system, compressive force generates the uniform tensile stresses in the sample. Magnetic characteristics are measured under these stresses by digitally controlled hysteresis graph. On the base of results of measurements the magnetoelastic characteristics of L17HMF steel casting were determined. Determined this characteristic is necessary to developed nondestructive testing method for monitoring of industrial and energetic constructions with elements made by L17HMF steel casting.

Opis:
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:
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.

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.

W referacie przedstawiono nowe możliwości zastosowania sensorów magnetosprężystych z rdzeniami z taśm amorficznych do pomiaru momentu skręcającego wytwarzanego w trakcie pracy zaworu kulowego. Wyniki pomiarów wskazują na w przybliżeniu liniową zmianę wartości momentu skręcającego w funkcji kąta obrotu trzpienia zaworu również w momencie początkowym, w którym konieczne jest pokonanie oporów wynikających z tarcia statycznego.
Measurements of torque during the operations of ball valve have great practical significance. Changes of value of torque may indicate malfunction of such valve. Paper presents new method of real-time measurements of torque in ball valve utilizing magnetoelastic sensors with amorphous alloy cores. Figure 1 presents the general, schematic block diagram describing operation of magnetoelastic sensor. In Figures 2 and 3 technical solution for magnetoelastic torque sensors is presented. In this solution uniform shearing stresses may be achieved in ring-shaped magnetoelastic core made of amorphous alloy. Figure 4 presents view of system for measurements of torque in ball valves, composed of magnetoelastic sensor, pneumatic actuator as well as 2 inch SNL ball valve. Results of experiments presented in Figure 5 indicate nearly linear characteristics of torque versus angle of valve's spindle. This phenomenon was observed also in initial range of valve operation, where static rubbing has to be overcame. Probably linear characteristic of torque versus angle is connected with the presence of elastic seal covering the ball in the valve.

Paper presents methodology of generation of the uniform, compressive or tensile stresses in ring-shaped amorphous alloys core. In this study we use the set of special nonmagnetic, cylindrical backings. These backings enabled the core to be wound as well as create the possibility of generation of uniform compressive and tensile stresses. Using presented methodology the magnetoelastic characteristics were experimentally determined for Fe40Ni38Mo4B18 Metglas 2826 MB amorphous alloy. Knowledge about these properties is important for users of inductive components with amorphous alloys cores due to the fact, that changes of fl ux density due to magnetoelastic effect exceed 40%.
W artykule przedstawiono metodykę zadawania jednorodnych naprężeń ściskających i rozciągających do rdzenia pierścieniowego wykonanego ze amorfi cznego stopu magnetycznie miękkiego. Do badań wykorzystano zestaw specjalnych, cylindrycznych nakładek wykonanych z materiału niemagnetycznego. Z wykorzystaniem tych nakładek powstała możliwość zarówno wykonania uzwojenia magnesującego i pomiarowego, jak również obciążenia rdzenia w zakresie naprężeń rozciągających i ściskających. Z wykorzystaniem przedstawionej metodyki zbadano charakterystyki magnetosprężyste stopu amorfi cznego o składzie Fe40Ni38Mo4B18 (Metglas 2826 MB). Wiedza w zakresie tych charakterystyk jest ważna z punktu widzenia dla użytkowników elementów indukcyjnych z rdzeniami ze stopów amorfi cznych. Należy podkreślić, że pod wpływem naprężeń mechanicznych, wartość maksymalnej indukcji magnetycznej B w rdzeniu może zmieniać się nawet o 40%. Unauthenticated

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.

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.
