Opis:: Tomography is a useful tool for objects reconstruction in non-destructive testing. Many kinds of tomography, depending on the penetrating wave character, are available and adapted for specific application. This paper presents new kind of tomography - conductance tomography extended with a Hall effect. Its development was motivated by the need on inhomogeneity detection in thin film Hall effect sensor, particularly graphene Hall effect sensors. Paper presents complete description of the tomographic method and tomography software developed in the GNU Octave. Inverse transformation is based on optimization method. Each shape reconstruction was done with the finite element method using the open source software: Elmer FEM and Salome. Results confirmed the suitability of the work.

Opis:: The paper presents results of research on the effects of mechanical stresses on the magnetostrictive properties of 13CrMo4-5 steel. Measurements of stress dependence of magnetostriction fill the gap in the state of the art enabling description of relationships between stresses applied to the samples and its magnetoelastic and magnetostrictive properties. Performed studies represent the starting point for development of unified model of both Villari (magnetoelastic) and Joule (magnetostrictive) effects under stresses in steels. The formulated model will be the basis for the development of generalized methods of interpreting the results of non-destructive testing of the state of the internal stresses in steels based on these phenomena.
