This paper concerns the possibility of use of the Jiles-Atherton-Sablik extended model to describe the magnetic characteristics for construction steel ST3. Result of the modelling utilizing extended Jiles-Atherton-Sablik model are in good agreement with results of experimental measurements for magnetic hysteresis loops B(H). However experimental results indicated, that the influence of temperature on B(H) characteristics is relatively small and can be neglected from the point of view of modelling for technical applications, such as stress estimation for non-destructive testing. © (2013) Trans Tech Publications, Switzerland.

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. © (2013) Trans Tech Publications, Switzerland.

Paper presents the results of investigation on the tensile stresses dependence of magnetic characteristics of the heat resistant 13CrMo4-5 steel. For this investigation, the frame-shaped samples were used. 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 resistant 13CrMo4-5 steel were determined. These characteristics indicate that change from elastic to plastic deformation significantly changes the magnetic properties of this steel. This information has great technical importance from the point of view of non-destructive testing of construction elements made of heat resistant 13CrMo4-5 steel. © Springer International Publishing Switzerland 2015.
